X-STREAM X2

INTRODUCTION

The instruction manual contains information about the component assembly, function, installation, operation and maintenance of the X-STREAM® X2 series gas analyzers.

The manual covers several X-STREAM analyzer models and so many contain information

about congurations and/or options not appliccable to your analyzer.

The installation and operation of units for use in explosive environments is not covered in this manual. Analyzers intended to be used in such environments are supplied with further instruction manuals, which should be consulted in addition to this.

DEFINITIONS

The following denitions explain the use of the terms WARNING, CAUTION and NOTE in

this manual.

Safety Instructions

Indicates an operational or maintenance procedure, a process, a condition, an instruction, etc.

Failure to comply may result in injury, death or permanent health risk.

Indicates an operational or maintenance procedure, a process, a condition, an instruction, etc.

Failure to comply may result in damage to or destruction of the instrument, or impaired performance.

NOTE!

TERMS USED IN THIS INSTRUCTION MANUAL

Instruction Manual

HASX2E-IM-HS

02/2012

Explosive Gas(es)

Flammable Gases and gas mixtures in a mixture with air within the explosive limits.

Flammable Gas(es)

Gases and gas mixtures are assigned to be ammable if they might become ignitable

when in a mixture with air.

Infallible Containment

This term is derived from the standards of explosion protection especially from the requirements for pressurized housings: thus an

infallible containment can be characterized by no intended leakage into the gas paths enabling gas to enter the inner compartment

of the analyzer housing.

Intrinsically Safe Cell (IS Cell)

Cells supplied with an intrinsically safe power

signal, approved by a Test Institute, to operate

with explosive gases. The design ensures the IS cells remains safe even in case of failure and explosive gases are not ignited.

Protection Class IP66 / NEMA 4X

Both terms are used to specify conditions for

equipment to be installed outdoor.

Power supply

X-STREAM X2

Safety Instructions

Ensure that the local power voltage where the unit is to be installed, corresponds to the unit’s nominal voltage as given on the name plate label.

CONNECTING UNITS FOR PERMANENT INSTALLATION

Only qualied personnel following all applicable and legal regulations

may install the unit and connect it to power and signal cables. Failure to comply may invalidate the unit’s warranty and cause exposure to the risk of damage, injury or death.

This unit may only be installed by qualied personnel familiar with the

possible risks. Working on units equipped with screw-type terminals for electrical

connections may require the exposure of energized components.

Wall-mounted units have no power switch and are operational when connected to a power supply . The operating company is therefore required to have a power switch or circuit breaker (as per IEC 60947-1/-3) available

on the premises. This must be installed near the unit, easily accessible to operators and labelled as a power cut-off for the analyzer.

Safety Instructions

ADDITIONAL NOTES FOR UNITS WITH SCREW-TYPE TERMINALS

Cables for external data processing must be double-insulated against mains power.

If this is not possible, cables must be laid in such a way as to guarantee a clearance of at least 5 mm from power cables. This clearance must be permanently secured (e.g. with cable ties)

General Operating Notes

General operating notes

EXPLOSION HAZARD

Exhaust gases may contain hydrocarbons and other toxic gases such as carbon monoxide. Carbon monoxide is toxic.

Faulty gas connections may lead to explosion and death. Ensure that all gas connections are connected as labelled and airtight.

• The unit must be installed in a clean and dry area protected from strong vibrations and

frost

• The unit must not be exposed to direct sunlight and sources of heat. Admissable ambient temperatures (see technical details) must be adhered to.

• Gas inlets and outlets must not be interchanged.All gases must be supplied to the unit already

processed. When using this unit with corrosive sample gases, ensure that these gases do not contain components harmful to the gas lines.

• Admissable gas pressure for sample and test gases is 1500 hPa.

• Exhaust lines must be laid inclined downwards, depressurized, protected from frost and according to applicable regulations.

• If it is necessary to disconnect the gas lines, the unit’s gas connectors must be sealed with

PVC caps to avoid polluting the internal gas lines with condensate, dust, etc.

• To ensure electromagnetic compatibility (EMC), only shielded cables (supplied by us on

request, or of equivalent standard) may be used. The customer must ensure that the shiel-

ding is correctly tted ( section 4.5, page 4-31). Shielding and terminal housing must be electrically connected; submin-D plugs and sockets must be screwed to the unit.

• When using optional external adapters (submin-D to screw-type terminal), protection from electromagnetic interference can no longer be guaranteed (CE compliance pursuant to EMC

guidelines). In this case the customer or operating company functions as a maker of a system and must therefore ensure and declare compliance with EMC guidelines.

HASX2E-IM-HS 02/2012

1.1 Overview

X-STREAM X2

1.1 Overview

All X-STREAM gas analyzers feature an easy-to-use alphanumeric user interface, which displays measurement values, status and error messages, and menus for the input of parameters.

1.1.1 The Front Panel

All X-STREAM gas analyzers feature an alphanumeric LCD display with 4x20 characters, showing measurement and status information.

Wall-mounted units can, as an alternative, be

tted with a vacuum uorescent display, incre-

asing legibility in brighter environments.

The

display can also be protected with an impact

tested glass panel. All analyzer types also feature three LEDs on

the front panel which display status information in addition to the plain text messages.

For ease of use, the operator can select one

of ve languages for the display (currently available: English, French, German, Italian

and Spanish).

The colors of the LEDs are based on the

NAMUR NE 44 specifications. The LEDs are activated in accordance with the NE 107

standards, and indicate “Failure”, “Function check”, “Out of specication” and “Maintenance request”. For further information, see

chapter 8, page 8-1.

The analyzer software is operated by means

of only six keys.

1.2 Conguration of Gas Lines

1.2 Configuration of Gas Lines

Various materials are available to allow the analyzer to be customized to your needs. The materials used are selected based on

the characteristics of the sample gas, e.g. diffusion rate, corrosiveness, temperature and pressure.

1.2.1 Materials Used

The physical and chemical properties of the sample gas as well as the conditions under

which measurement takes place inuence the choice of materials. Among those available

are Viton

, PFA and stainless steel.

1.2.2 Safety Filter

The analyzers are generally tted with an internal stainless-steel lter. This lter is not

a replacement for any dust lter in the prepa-

ration of the gas, but represents a last line of

defence.

1.2.3 Inlets and Outlets

Rackmounted and tabletop devices are tted

with PVDF inlets and outlets (ø 6/4 mm) as standard. Alternatively, Swagelok™ or stain-

less steel ttings (ø 6/4 mm or ¼ in can be tted.

Wall-mounted eld housings are supplied with Swagelok™ or stainless steel ttings (ø 6/4 mm or ¼ in) ausgestattet.

Other materials available on request.

X-STREAM X2FD units are always supplied

with ame arrestors and stainless steel ttings (ø 6/4 mm or ¼ in).

1.2.4 Pipework

Unless otherwise specied, the analyzers

are supplied with Viton® or PVDF piping (ø

6/4 mm or ¼ in). Other materials (e.g. stain-

less steel) can be used, depending on the

application.

1.2.5 Infallible Containments

Infallible containments are gas lines which,

due to their design, can be regarded as per-

manently technically tight. This is achieved

by, for example, welded joints, or metallically

sealing joints (e.g. tap connectors and bin-

ders), providing they are seldom disconnec-

ted. Gas lines congured in this manner can be used for measuring noxious, ammable

and explosive gases. At the time of going

to press, infallible containments for thermal

conductivity analysis (TC) are available; other

analysis methods are projected. Further in-

formation about infallible containments can be found in the separate instruction manual

supplied with these units.

Infallible containments do not render it unnecessary to test for leaks regularly, e.g. following lengthy breaks in service, substantial alterations, repairs and

modications.

Read the separate instruction manual giving detailed instructions on the conguration, operation and maintenance of units fitted with infallible containments.

1.2 Conguration of Gas Lines

1.2.6 Optional Components for Gas Lines

X-STREAM X2

The analyzers can, as an option, be tted with

further components. Not all components are

available for all analyzer types:

• internal sample gas pump

• internal valve block

• internal ow sensors

• internal ow monitor switch

• internal barometric pressure meters

• internal temperature sensors.

1.2.6.1 Internal Sample Gas Pump

An internal sample gas pump is used when

the sample gas is under insufcient pressure. It ensures a constant ow of sample gas (max.

2.5 l/min through the analyzer).

When in internal pump is tted, the relevant

parameter in the software setup dialog is set to Yes ( 6.2.3.5, page 6-43). The pump

can be controlled either manually through a software menu or optionally by a digital input.

1.2.6.2 Internal Valve Block

The use of an internal valve block allows all

necessary gas lines (zero gas, span gas, sample gas) to remain permanently connected to the analyzer. Valves are then activated automatically when required (e.g. during au-

tomatic calibration). When an internal valve block is tted, this is

shown in the relevant software setup dialog as either Internal or Int+Ext (

page 6-43). The valves are controlled by either a software menu, optionally by digital input, or automatically during autocalibration.

Depending on the model, up to two valve

bocks can be tted.

6.2.3.5,

1.2.6.3 Internal Flow Sensor

Up to two internal ow sensors can measure

the ow of gas and can activate an alarm si-

gnal in the event of a failure. The alarm level

for ow sensors is operator adjustable to up

to 2000 ml/min. Depending on the model, up

to two sensors can be tted and evaluated

separately. When a sensor is tted, the relevant parame-

ter in the software setup dialog is set to Yes (

6.2.3.5, page 6-43).

If the current ow rate is too low, a status

message is displayed and the parameter under CHECK REQUESTS.. is set to Yes

( Chapter 8 “Troubleshooting”).

1.2.6.4 Internal Flow Monitor Switch

An internal ow switch monitors the gas ow

and activates an alarm signal in case it is not

sufcient. The alarm level for the internal ow switch is xed and not operator adjustable.

Additional external switches may used and

connected via digital inputs. All tted ow

switches are evaluated to share a common alarm.

When an internal ow switch is tted, the relevant parameter in the software setup dialog is set to Yes (

If the current ow rate is too low, a status

message is displayed and the parameter under CHECK REQUESTS.. is set to Yes

( Chapter 8 “Troubleshooting”).

1.2 Conguration of Gas Lines

1.2.6.5 Internal Barometric Pressure Sensor

The inuence of varying atmospheric pres-

sure can be compensated for by the use of an internal barometric pressure sensor ( measurement specication, page 3-17).

If such a sensor is installed in the unit, the related menu shows the entry Internal (

6.2.3.5, page 6-43).

1.2.6.6 Internal Temperature Sensors

The inuence of varying temperatures can be compensated for by the use of internal

temperature sensors (

measurement

specication, page 3-17 ). Depending on the conguration of the unit or

the demands of the application, temperature sensors can measure the unit’s internal temperature or selected measurement channel components.

If such sensors are installed in the unit, this is indicated in the installed options menu (

6.2.3.5, page 6-43).

1.2.6.7 Optional Heated Area

X-STREAM X2

1.2 Conguration of Gas Lines

The physical components can be optionally

separated from the electrical components

by means of a special box (not an option for ½ 19 in units). This can be done for one or both of the following purposes:

Firstly, the box allows the physical components to be regulated to a temperature of ap-

prox. 60°C, avoiding condensation of gases

or the inuence of varying environmental

temperatures.

Secondly, the box can be purged with, for example, inert gas. The purge gas is rst fed

through a separate tting, purges the elec-

tronic components, then oods the box and leaves the instrument via another tting.

Purging in this manner can be useful when

measuring very low concentrations (e.g. of

CO or CO

): the expulsion of ambient air

avoids adulterant outside inuences. Alternatively, purging can be used to secure

enhanced protection for electronic parts and operators from corrosive or toxic gases: any leaking gas is expelled from the housing and does not escape into the vicinity of the unit or come into contact with any electronic compo-

nents located outside the box. In either case, the purge gas outlet should be

connected to an exhaust gas line.

1.3 Interfaces

X-STREAM X2

1.3 Interfaces

All analyzer types are tted with one analog

electrical output for each channel and four status relays as standard.

As an option, further interfaces can be added.

1.3.1 Analog Outputs

Each X-STREAM analyzer is tted with one

output per channel as standard, which can transmit data on concentration levels to an external data acquisition system.

The mode of operation (e.g. 4-20 mA, 0-20 mA) and support for NAMUR NE 43

specications (incl. Live Zero) can be set in a

software menu ( 5.7.4, page 5-20). The factory setting for analog outputs is

4-20 mA.

Depending on the unit conguration, all in-

terfaces are accessible via either SubminD

connectors or screw terminals

X-STREAM analyzers support up to four analog outputs, which, however, do not always need to be assigned to measurement channels which are physically present: if a unit has less than four channels, the remaining analog

outputs can be used to transmit concentration

levels with a different resolution; for example,

a single-channel analyzer could be set up as

follows:

Output 1: 0…100 % CO Output 2: 0…25 % CO

= 4…20 mA

Technical Description

1.3.2 Status Relays

By default, the four relays are congured to

signal the current status of the unit according to the

NAMUR NE 44 recommendations

(“Failure”, “Maintenance request”, “Out of

specication” and “Function check”). Howe-

ver , the operator can assign different functions to the relays via software menus. For more

The contacts, which can take a maximum load

of 30 V at 1 A and 30 W, can be operated as

quisition systems. The interface enables the exchange and modication of measurement

and analyzer signals as well as the remote activation of procedures.

The RS 485 interface is electrically isolated from the unit’s electronic components and facilitates the construction of a network of several analyzers.

Optionally, an RS 232 interface can also be

used (and is also electrically isolated from the unit’s electronic components; however,

it only allows communication between two

end devices.

1.3.3.2 Modbus Interface, Ethernet

The Ethernet Modbus interface offers the

same form of comunication with a data acquisition system as does a serial interface.

The most obvious difference is the plug-and-

socket connection: the Ethernet interface uses an RJ45 socket.

This interface is also electrically isolated from the unit’s electronic components and enables the construction of a network of several analyzers.

All supported Modbus parameters are listed

in chapter 9.

Note!

The Ethernet Modbus interface cannot be combined with the serial Modbus interface (

1.3.3.1).

1.3.3.3 Digital Outputs

X-STREAM X2

1.3 Interfaces

Digital outputs can be used for various purposes:

• Issuing concentration alarms: Process control systems can detect when limits are exceeded and trigger appropriate actions.

• Switching external components: For ex-

ample, during automatic calibration, the necessary valves can be activated directly by the analyzer.

1.3.3.4 Digital Inputs

Digital inputs can:

• trigger calibration procedures, for example by a process control system

• remotely control valves and the optional

sample gas pump (in concert with correctly

congured digital outputs).

Digital inputs can be integrated into the units

in groups of 7 or 14 (

1.4, page 1-12).

Digital outputs can be integrated into the units

in groups of 9 or 18 (

1.4, page 1-12).

The relay contacts, which can take a maxi-

mum load of 30 V at 1 A and 30 W, can be operated as normally open (NO) or normally

closed (NC).

Instruction Manual

HASX2E-IM-HS

02/2012

This compact model for general purposes

can be tted with up to three measurement channels in various combinations. Power is

supplied by an internal wide range power sup-

ply or a separate external power supply unit.

By default the units are congured for tabletop use. A carrying handle is optional available

which makes it easy to take the instrument to varying sampling points. For rack mounting a

X2GK is xed by screws located at the front

panel.

Front panel

The analyzer’s front panel consists of one 4x20-character alphanumeric LCD display, a

membrane keyboard and three status LEDs (Fig. 1-4). The colors of the LEDs are based on the NAMUR NE 44 specications. The LEDs

are activated according to the NE 107 standards and correspond to the following status

messages: “Failure”, “Function check”, “Out of specication” and “Maintenance request”.

Connection to power supply

AC is supplied by an IEC chassis plug with

power switch and fuse holders. The internal

wide range power supply unit enables the analyzers to be used worldwide. DC 24 V

power is supplied via a 3-pin socket at the rear of the unit.

Interfaces

The electrical connections for interface sig-

nals are provided via submin-D connectors, also mounted at the back of the unit (Fig. 1-4).

For applications where screw-type terminals are preferred for connecting signal wires, op-

tional adapters are available, which are moun-

ted directly onto the submin-D connectors.

pin submin-D socket terminal strip is always

included, providing one analog output (4-20 or 0-20 mA) and the contacts for the four NAMUR status relays.

Further analog outputs can also be provided,

e.g. to provide a measurement signal at different resolutions. A maximum of four analog

outputs are possible. A serial Modbus interface can also be installed

on request (RS 232 or RS 485 with Modbus

RTU protocol, via 9-pin submin-D male con-

nector

); alternatively an RJ45 socket can also

give access to Ethernet-Modbus-TCP. Digital inputs and outputs can be used to

control analyzer functions and external components. The 7 inputs and 9 outputs are connected to peripheral devices via a 37-pole

submin-D socket terminal strip.

Detailed technical details on the various inter-

faces can be found in

1.3, page 1-9. The

conguration of the connectors are described

in chapter 4 “Installation” and the software settings in chapter 6 “Software”.

A further submin-D socket, which is not in detail described in this manual, is also located

at the rear of the unit, and is designated as a Service Interface.

The Service Interface is electrically connected to the unit’s electronic components. If it is incorrectly handled, damage to the unit may result. The Service Interface may only be used by EMERSON service personnel or specially trained staff.

Gas connections

Depending on the conguration of the unit (number of measurement channels and serial

or parallel connection), sample and calibra-

tion gases are fed into the unit via up to 8

tube ttings mounted on the rear panel. The conguration of the ttings is indicated on an adhesive label located near the tube ttings.

Any free tube ttings can be used for purging

the device with

•

inert gas to minimize interference from the

ambient atmosphere when measuring small concentrations (e.g. of CO

)

•

air or inert gas when measuring corrosive

and/or ammable gases.

For further information, see page 1-5.

Special components

For the analysis of aggressive and/or am-

mable gases, infallible components (WLD; photometer under development) can be used.

The risk of an uncontrolled release of gases

due to a leak can be minimized by the use

of stainless steel piping and clamping rings. Further details about the infallible containment are in the separate manual supplied with units containing such parts.

Furthermore, intrinsically safe measuring cells, which prevent the ignition of gas mix-

tures in the case of a failure, can also be

used.

Modul variation XCC

The ½19-in unit is also available as an ana-½19-in unit is also available as an analyzer module without the front control panel,

which can, for example, be integrated into a

measuring system in which control and ana-

lysis of data is performed via interface by an

external data acquisition system.

1.7 X-STREAM X2XF Field Housings

1.7 X-STREAM X2XF: Field Housing With (XLF) Single Or (XXF) Dual Compartment

02/2012

Field housings are conceived for outdoor use and wall-mounting. The coated stainless steel housing has a protection class rated at IP66 / NEMA 4X, offering protection against water and dust entering the device:

IPx6: In case of occasional ooding, e.g. heavy seas, water shall not enter in harmful quantities

IP6x: Protection against penetration by dust. Live or internal moving parts are completely protected.

An X-STREAM eld housing can be tted with

up to four measurement channels in any com-

bination. The physical components can op-

tionally be encased in a cover. This separate volume can be held at a specic temperature

of up to 60 °C to minimize interference from changes in external temperature.

Front panel

The analyzer’s front panel consists of one 4x20-character alphanumeric LC display, a

membrane keyboard and three status LEDs

(Fig. 1- 6).

The colors of the LEDs are based on

the NAMUR NE 44 specications. The LEDs

are activated according to the NE 107 standards and correspond to the following status

messages: “Failure”, “Function check”, “Out of specication” and “Maintenance request”.

A vacuum uorescent display can be tted

instead of the LCD, making the information

displayed more easily readable in low light-

levels. The display is covered by an impact te-

sted glass to protect it in harsh environments.

Electrical connections

Electrical connections are provided via inter-

nal tube ttings, the cables being fed through cable glands at the right side of the unit (Fig.

1-8). The front cover of the housing swings

open to the left once the fasteners have been

released.

Connection to power supply

Mains power is supplied via the screw-type terminals with integrated fuse holders at the right of the housing, near the front. The wide range power supply unit mounted internally enables the analyzers to be used worldwide.

Interface signals

In the basic conguration, the unit has 36 internal screw-type terminals for interface signals, providing one analog output (4[0]-20 mA) and the contacts for the four (NAMUR) status relays. Further analog outputs can also

be provided, e.g. to provide a measurement

signal at different resolutions. A maximum of

four analog outputs is possible. A serial Modbus interface can also be installed

on request (RS 232 or RS 485 with Modbus

RTU protocol

); alternatively an RJ45 socket

gives access to Ethernet-Modbus-TCP. Digital inputs and outputs can be used to

control analyzer functions and external components. The 7 inputs and 9 outputs are connected to peripheral devices via a further

36-terminal strip. The number of digital inputs and outputs can be doubled (to 14 inputs and 18 outputs) by adding a second card and an

additional 36-terminal strip. Detailed technical information on the various

interfaces can be found in

1.3, page1-9

The conguration of the terminals is described in chapter 4 “Installation” and the software

Electrical connections

Electrical connections are made via internal screw-type terminals; the corresponding

cables are fed through cable inlets on the

underside of the unit into the housing (Fig. 1-12). The front of the unit opens downwards once the screws located on the surrounding

ange are removed

Power supply

Mains power is connected via screw-type terminals with integrated fuses, located in the front right-hand area of the housing. The internally mounted wide range power sup-

ply unit ensures the analyzers can be used

worldwide.

Interface signals

In the basic conguration, the unit has 36

internal screw-type terminals for interface signals, providing one analog output (4–20 or 0–20 mA) for each channel and the contacts for the four NAMUR status relays. Further

X-STREAM X2

analog outputs can also be provided, e.g. to

provide a measurement signal at different resolutions. A maximum of four analog outputs

is possible. A serial Modbus interface can also be installed

on request (RS 232 or RS 485 with Modbus

RTU protocol

); alternatively also access to

Ethernet-Modbus-TCP. In this case the RS

interface signals are routed to the appropriate

number (up to 5) of the 36 terminals. Digital inputs and outputs can be used to

control analyzer functions and external components. The 7 inputs and 9 outputs are connected to peripheral devices via a further

36-terminal strip. The number of digital inputs and outputs can be doubled (to 14 inputs and 18 outputs) by adding a second card and an

additional 36-terminal strip. Detailed technical information on the various

interfaces can be found in

1.3, page 1-9

The conguration of the terminals is described in chapter 4 “Installation” and the software

settings in chapter 6 “Software”.

A further submin-D socket, which is not in detail described in this manual, is also located

at the rear of the unit, and is designated as a Service Interface.

ded for the supply of sample and calibration

gases. The assignments of the connectors is

given on an adhesive label situated near the

connectors.

Optional two of the ttings may be used to

purge the housing with either

• inert gas to minimize interference from ambient atmospheres when measuring very small concentrations (e.g. CO

)

or:

• air or inert gas when measuring aggres-

sive and/or ammable gases.

For further information, see

section

1.2.6, page 1-5.

Special components

For the analysis of aggressive and/or am-

mable gases, and depending on the analysis method used (photometer or TC), infallible components can be used. The risk of an

uncontrolled release of gases due to a leak

can be minimized by the use of stainless steel

piping and clamping rings. Furthermore, for measuring oxygen in ammable atmospheres, intrinsically safe measuring cells, which prevent the ignition of gas mixtures in the case

of a failure, can also be used.

Gas connections

Depending on the conguration of the unit

(number of channels, series or parallel piping), up to eight ame arresters are provi-

Measuring Principles

X-STREAM series analyzers support several measuring principles depending on the gas

component of interest. This provides best possible results, as the measurement can be chosen to optimally t the characteristics of

the gas to be measured with respect to the ap-

plication. The following sections introduce the

available measuring principles highlighting their specic characteristics.

3.1 Infrared Measurement (IR) Ultraviolet Measurement (UV)

The non-dispersive measurement methods

described in this section utilize gas specic

light absorption in order to discriminate bet-

ween different gases. This is possible, as

any gas possesses distinct absorption cha-

racteristics. Selective measurement of these

so called absorption lines can be used to

identify gas components: The amount of light

absorpted by the absorption lines, is a direct

measure of the gas concentration.

One can distinguish between two different

types of non-dispersive measurements, differing in the way, wavelength selectivity is

accomplished. It is essential for gas specic

concentration measurements, to selectively detect only light of the absorption line wavelengths of the gas of interest. T ypically a gas selective detector is used for NDIR measurements,

is achieved by an additional optical lter, as the detector itself is broadband sensitive. In

some applications, a pyrodetector is used for NDIR measurements. This type of detectors is not wavelength selective, hence these se-

tups also use an optical lter to narrow their

wavelength response function.

The assembly of a NDIR and NDUV channel

is shown in

3-3. For NDUV the selectivity

Fig. 3-3. For NDIR a broad-

band IR light source is used to generate the

light, while NDUV measurements utilize a UV

narrowband uorescence source or an EDL

(Electrodeless Discharge Lamp), already

adopted for the absorption lines of the gas of interest. Part of this adoption is done by a specially selected optical lter in the adaptor

cell.

The diameter of the light beam emitted from the sources is adjusted to completely ll the

opening of the split analysis cell. After traversing the analysis cell, the light passes through

a lter cell which adjusts the beam diameter to

the chopper opening and the diameter of the active detector area. The chopper wheel used is designed to allow an intrinsically referenced measurement. The details of this new method

are described in

The decision, which measurement (UV / IR)

to be used for a specic application depends on the gas component to be measured, and

the required measurement performance.

3.1.1 IntrinzX Technology

The IntrinzX technology is an enhancement of

the well established “proof peak” technology

with automatic sensitivity control, known from

the MLT gas analyzer series. While the “proof peak” provided one reference measurement

per chopper wheel revolution only , the IntrinzX technology provides four reference measurements per revolution. This IntrinzX technology

has been introduced into the market with the

launch of the X-STREAM X2 gas analyzers. Using the new IntrinzX chopper wheel, the

reference and the measurement signal are modulated with 4 and 5 times the basic revolution frequency. As a result, the proof peak

process is integrated into the measurement

information, in contrast to being articially

inserted in the measurement signal.

Frequency ltering separates the sum signal

into measurement and reference signal (

Fig. 3-1). This results in a permanently

referenced signal by dividing the integrated

reference level by the integrated measure-

ment level for each revolution. Therefore the IntrinzX technology provides

many outstanding features:

• High dynamic measurement ranges (e.g.

0-200 to 50,000 ppm CO), which cannot be obtained with standard photometric

technologies

• Reduced temperature dependency

• High sensitivity for lowest measuring

ranges

This leads to cost saving effects for the customer:

• Fewer number of benches & cells

• Easier eld repair and replacement of

parts

• Easy adjustment of low measuring ranges

in the eld

• Reduced maintenance

• Extended span calibration intervals

• Minimized demand for test gases Due to the inherent correlation between refe-

rence and measurement side, span calibrati-

on can often be achieved by zero calibration. The above listed IntrinzX features offer a

high degree of exibility with regards to ap-

plications:

• One bench enables measurements of low & high ranges

• Low & high concentration in raw and clean

gases

• Low and high ranges before and after scrubbers

• Measurement of carbon bed breakthrough /

catalyst efciency

• Mobile measurements at different samp-

ling points / locations

• Easy adaption to different applications

(universities, laboratories)

• Supports automotive engine testing

• Benches to be used in TOC applications for measurements of low and high carbon

3.1 Infrared (IR) and Ultraviolet (UV) Measurement

3.1.2 NDIR Detector

X-STREAM X2

The standard detector used for NDIR measurements is an opto pneumatic detector.

It consists of two chambers, lled with gas and

connected via a small channel ( Fig. 3-2).

The gas lling is chosen to provide maximum overlap with the gas to be measured. Usually the gas to be measured itself is used.

A micro ow sensor, placed in the connecting channel, measures the ow between both chambers. As light is absorbed by the gas in the absorption chamber, the gas temperature

changes. This results in an increase of volume

of the heated gas: The gas expands and ows towards the compensation chamber. When the chopper closes, no light is absorbed and

thus temperature and volume of the gas in

the absorption chamber decrease. Gas ows back from the (now) hotter compensation chamber into the absorption chamber. The

absolute ow, detected by the micro ow sen-

sor, in both cases is therefore a measure for the light absorbed while the chopper is open.

This directly correlates to the amount of light

not absorbed in the analysis cell and therefore

to the concentration of the measurement gas inside the analysis cell.

Using the divided analysis cell and the IntrinzX chopper wheel, this enables simultaneous detection of measurement and reference signal.

The radiation emitted by an IR or UV/EDL

source passes an adaptor cell, widening the

beam to completely ll out the analysis cell´s

diameter. At the opposite side of the cell, another adaptor cell is installed to reduce

the beam to the diameter of the opening in

the chopper. The detectors are installed at the rear side

of the chopper.

As pyrodetectors are not as

frequency selective as gas detectors, an ad-

ditional lter has to be installed when using

pyrodetectors, limiting the bandwidth of radi-

ation passing the chopper.

3.2 Oxygen Measurement

Two different principles are used for measuring oxygen concentrations. The currently

used principle is given by the channel code

(sample gas designator) on the nameplate

label (

see gure on page 2-21): pO2 = paramagnetical sensor eO2 = electrochemical sensor

3.2.1 Paramagnetic Measurement

Oxygen measurement is based on the para-

magnetical characteristics of oxygen molecules:

Two nitrogen lled quartz spheres (N

is not

paramagnetic) are arranged in a dumbbell conguration and, hinged to a platinum wire,

placed inside a cell. Fixed to the wire a small

mirror reects a light beam to a photo detector (g. 3-7).

The measuring cell is placed inside an in-

homogeneous magnetical eld generated by a strong permanent magnet of specic

design.

Oxygen molecules within the sample gas now

due to their paramagnetical characteristics

are deected into the area of highest eld

strength. This generates different forces on

both spheres and the resulting torque turns dumbbell and mirror out of the rest position.

This generates a photodetector signal becau-

se the beam is deected, too. Initiated by the photodetector signal a pre-

amplifier drives a compensation current

through a loop surrounding the dumbbell to turn back the dumbbell into the rest position by effect of a magnetic eld

So the current compensating the torque

affec-ting the dumbbell is a direct measure for

the oxygen concentration within the sample gas.

In addition to measuring cell, permanent magnet, electronics and enclosure the paramagnetic oxygen detector contains a temperature sensor and a heating element to hold the detector at approx. 55 °C.

Several variations are available including

corrosion resistant, solvent resistant and/or

intrinsically safe (for measuring ammable

gases) versions.

The electrochemical oxygen sensor‘s key components are a lead anode (1) and a gold

cathode (2) surrounded by a special acid

electrolyte (3). The gold electrode is integrated solid with the

membrane,which is a non-porous uororesin membrane. Oxygen which barely diffuses through the membrane is electrochemically

reduced on the gold electrode. The temperature compensating thermistor

and adjusting resistance are connected between the cathode and anode. The current

generated by oxygen reduction is converted into a voltage by these resistances.

The value of the current owing to the thermi-

stor and resistance varies in proportion to the oxygen concentration of the measuring gases

which contact the membrane. Therefore, the

voltage at the terminal of the resistances is used for the sensor output to measure the oxygen concentration.

In consequence of its design the sensor‘s lifetime is limited and depends on theoretical designed life and oxygen concentration. The sensor output can be taken as a rough criterion for end of lifetime: The sensor is weared

The sensor‘s designed lifetime under constant conditions of ambient temperature 20 °C is approx. 900,000 % hrs.

The lifetime at 21 % oxygen is then calculated to approx. 42,857 hrs, corresponding to

approx. 5 years.

An indicator for end of lifetime is a reduced

output signal. In this case the sensor must be

replaced to ensure accurate measurements (

Note!

The given values are for reference only! The expected lifetime is greatly affected by the temperature of the environment in which the sensor is used or stored (operation at 40 °C halves lifetime).

3.2 Oxygen Measurement

Due to the measuring principle the electrochemical oxygen cell requires a minimum internal consumption of oxygen (residual humidity avoids drying of the cell). Supplying cells continuously with dry sample gas of low grade oxygen concentration or with sample

gas free of oxygen could result in a reversible detuning of O

sensitivity. The output signal

will become unstable, but response time remains constant.

For correct measurement the cell needs con-

tinuously to be supplied with concentrations of at least 0.1 Vol.-% O

. We recommend to

use the cells if need be in alternating mode,

means to purge cells with conditioned (not

dried, but dust removed) ambient air when

measurement pauses. If it is necessary to interrupt oxygen supply

for several hours or days, the cell has to re-

generate (supply cell for about one day with ambient air). Temporary ushing with nitrogen

) for less than 1 h (e.g. for analyzer zero-

ing purpose) has no inuence on measuring characteristics.This sensor is not suitable

for anorganic gases containing chlorene or

ourene!

In addition it is not suitable for sample ga-

ses containing ozone, H

S (> 100 ppm) or

NH3 (> 20 ppm).

3.2.3 Electrochemical Trace Oxygen Measurement

X-STREAM X2

For trace oxygen measurements (tO

electrochemical sensor technology is used, see Fig. 3-9. The sensor is a self contained disposable unit which requires no maintenance. The sensor utilizes the principle of electrochemical reaction to generate a signal proportional to the oxygen concentration in the sample.

Fig. 3.9 Trace Oxygen sensor design principle

The sensor consists of a cathode and anode

which are in contact via a suitable electrolyte. The sensor has a gas permeable membrane

which covers the cathode allowing gas to pass into the sensor while preventing liquid electrolyte from leaking out.

As the sample diffuses into the sensor, any oxygen present will dissolve in the electrolyte solution and migrate to the surface of the cathode. The oxygen is reduced at the cathode. Simultaneously, an oxidation reaction is occurring at the anode generating four

electrons. These electrons ow to the cathode

to reduce the oxygen. The representative half cell reactions are:

Cathode

This ow of electrons constitutes an electric

current which is directly proportional to the concentration of oxygen present in the sam-

ple. In the absence of oxygen, no oxidation/

reduction reaction occurs and therefore no current is generated. This allows the sensor

to have an absolute zero.

3.2.3.1 Special Hints This sensor is a consumable

and requires replacement periodically. (To determine if the sensor requires replacement, see the troubleshooting section of this manual)

Remaining lifetime counts down when the sensor is in contact with oxygen.

For above reasons, the analyzer is shipped with the sensor as extra item in a sealed bag!

The sensor must be installed before analyzer startup, according the instructions shipped with the sensor!

Always consult the separate instructions, shipped with the sensor, before intending to start calibrations! Violation may result in a damaged sensor!

After replacement purge gas paths with inert gas (nitrogen (N

) or sample gas as soon as

possible to avoid prolonged exposure of the

sensor to high concentrations of oxygen. The longer the sensor is exposed to air , the longer it will take for the sensor to recover to low ppm levels. When installing a new sensor or

starting the instrument for the rst time, it may

take as long as eight hours for the analyzer to purge down to the lowest operating range.

After initial startup or startup following a prolonged shutdown, the analyzer may require extended time to recover to the range of

measurement. Commonly, this is caused by the introduction of ambient air into the sample

and/or vent lines to the sensor. The presence

of higher than normal levels of oxygen at the sensor will cause the sensor electrolyte to become saturated with dissolved oxygen. When the instrument is placed in operation, the sensor must now consume all excess dissolved

oxygen above the desired measuring level. All analyzers with electrochemical tO

have to be purged with inert gas (Nitrogen, N

The bridge output signal (U

) is adjusted to

zero when in rest position (no gas ow). By

default the reference gas path is closed (not own through by gas). When sample gas is supplied, the sensors in the sample gas path are cooled due to the thermal conductivity ef-

fect: The gas absorbs heat and carries it away

from the sensors. This tunes the Wheatstone

bridge and generates a signal proportional to

the thermal conductivity. Additional electronics linearizes and conditi-

ons this signal to provide usefull measuring

values.Depending on application, it is possib-

le to supply a reference gas to the bridge‘s

reference side. The output signal in this case is proportional to the difference of the thermal conductivities of sample and reference gas.

water vapor to condense into water. The condensed water is called dew. The dew point is the saturation temperature.

is the temperature in Deg C

Humidity is the amount of water vapor in the

air. Relative humidity is dened as the ratio

of the partial pressure of water vapor (in a gaseous mixture of air and water vapor) to the saturated vapor pressure of water at a given temperature.

The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100 % indicates the dew point is equal to the current temperature and the air is maximally saturated with water. If the dew point remains constant and temperature increases, relative humidity will decrease.

3.4 Trace Moisture Measurement

How does dew point measurement connect with trace moisture measurement?

The lower the dew point of a gas, the less is the content of moisture within that gas.

3.4.1 Special Operating Conditions

The sensor is completely calibrated with all calibration data stored in its ash memory and does not require recalibration:

• If the sensor is included into a calibra-

tion procedure, it might end up with a

wrong calibration and unusable sensor.

Therefore the analyzer's trace moisture

measurement channel is congured to be excluded from autocalibration procedures, by default calibrating all channels. This exclusion is done by factory setup and cannot be changed.

• For proper measurement results we re-

commend to exchange the sensor regularly after 12 months of operation.

Tab. 3-10: Oxygen - Standard Measurement Performance Specications

Note 1!

Not all data listed are applicable to all analyzer versions (e.g. 60 °C thermostatically controlled box is not available for electrochemical and trace oxygen nor for

⁄219 in instruments).

Note 2!

For NDIR/UV/VIS measurements, take into account that

• sample gas may diffuse or be released by leakages into the analyzer enclosure

• if existent in the analyzer surroundings, the component to be measured may enter the enclosure.

Concentrations then may increase inside the enclosure. High concentrations of the component

to be measured inside the enclosure may inuence the measurement by unintended absorption,

which could cause drift of the measurement. A remedy for this issue is to purge the housing with gas not containing the component of interest.
