INTRODUCTION

1.1 Features

• There are 2 versions of the XTP601 available:

• The XTP601 is calibrated in a specific background gas to match customer's requirements. This is displayed on the front screen of the analyzer or via the Application Software.

• The XTP601 provides 2 off 4-20 mA analog output signals that are proportional to the oxygen concentration. The primary 4-20 mA output is locked on the calibrated range of the instrument. The secondary output is user-selectable within the calibrated range.

• Modbus RTU over RS485 protocol serial communications are provided as standard.

XTP601 User’s Manual

Analyzer with touch screen (capacitive buttons)

Transmitter (base model)

• Accuracy of 1% FS or 0.02% O ranges ±0.2% O2).

• Zero and span stability of 0.25% of span per month.

• The Thermo-Paramagnetic sensor used in the XTP601 Oxygen Analyzer has no moving parts. This makes it less sensitive to vibration and movement and highly resistant to drift over a long period of time, compared to other sensing technologies.

• Innovative sensor design which minimizes zero drift and offers increased protection against contamination.

• The robust and weather-proof enclosure (IP66 rated) allows the XTP601 to be installed on-site, at the point of measurement. It is also available

with an explosion-proof casing and certified to II 2 GD Ex d IIB+H2 T6 Gb, Ex tb IIIC T85°C Db IP66 T amb -40°C to +55°C. (Dependant on

O-Ring selection, see Section 1.3.)

• All of the analyzer functions can be accessed via the touch screen (capacitive) buttons (on display model), or via the Application Software.

• Low cost of ownership due to minimal maintenance. When required, the casing unscrews to allow for easy access to the sensor, enabling maintenance to be carried out quickly and easily.

, whichever is greater. (Zero suppressed

• The XTP601 is certified to ATEX, IECEX, cCSAus, INMETRO & TC TR Ex for use in hazardous areas.

• 2 x single pole change-over relay alarms for oxygen concentration, supplied as standard. Can be configured as OFF, LOW or HIGH on the analyzer (GP1 or EX1) version or LOW or HIGH on the transmitter (GP3 or EX3) version.

1.2 Applications

The XTP601 has a robust sensor with high sensitivity and stability. It can be factorycalibrated in varying backgrounds to match the customer’s process gas. The analyzer has a built-in local user interface with a display. The capacitive buttons work through the glass face, without needing to remove the lid.

Together with the purpose designed sampling system, the XTP601 is able to work under various process and environmental conditions. Examples of applications include:

• Monitoring inert blanketing gases

• Oxygen measurement at inlet of compressors in steel or gas industries for safety

• Biogas, waste, landfill and digester plants

• Inert gas for pharmaceutical industry and painting gas

INTRODUCTION

• Catalyst regeneration

1.3 O-Ring Selection

The XTP601 is available with 3 types of O-rings to offer greater flexibility with material compatibility. The Viton O-ring is fitted as standard. The EKRAZ O-ring is available for solvent resistance. For extremely low temperatures there is a closed cell Silicone O-ring.

To comply with Hazardous Area certification, the material used in the EX1 & EX3 versions is dependent on the lowest ambient temperature of the area the units are to be installed in:

Ambient operating range:

-40°C to +55°C (-40°F to +131°F) (for Silicone version)

-15°C to +55°C (5°F to +131°F) (for Viton version) - Standard

-10°C to +55°C (14°F to +131°F) (for Ekraz version)

XTP601 User’s Manual

The XTC601 is not certiﬁ ed for use with ambient oxygen

levels that are enriched (i.e. over 21% O2)

2.1 Preparation

Zero and Span gas cylinders with correct regulation and flow control should be in place before installing and powering up the analyzer. Commissioning should include a check with both gases and, if necessary, a field calibration performed.

All analyzers will be calibrated with an inlet pressure of 1 barg (14 psig) with an atmospheric vent and flow rate of 300 ml/min (0.63 scfh). The calibration gas applied to the analyzer should be at the same pressure and flow rate as the process gas being sampled.

Sample Inlet Pressure:

• 0 to 4 barg (0 to 58 psig)

Before applying power and beginning the ﬂ ow of gas,

please ensure that the system has been properly installed

following the instructions in Section 4.

Check that the wiring has been completed correctly.

Sample Flow Rate:

GP1 & GP3 models: 100 to 500 ml/min (0.2 to 1.06 scfh)

EX1, EX3 & GP2 Models: 270 - 330ml/min (0.54 to 0.66 scfh)

2.2 Powering up the Analyzer

After all the preparation work is done and the installation

and wiring have been checked, turn on the analyzer and

wait for at least 30 minutes (or until message disappears). This will allow the analyzer to

reach its operating temperature of +50°C (or +60°C if

higher temperature cell is chosen) and protect it from any

There is no power switch on the XTP601 Oxygen Analyzer. It is turned on automatically once a 24 V DC power source is applied. After the analyzer is powered up, the display will be illuminated. The analyzer takes up to 5 seconds to initialize, and during this period will display the product type and firmware version number.

A 4-20 mA sensor may be used to compensate the % O2 reading for the effects of process variables such as line pressure, flow, etc. The table of compensation factors may be edited for 5 points along the compensation sensor range. The values would be determined by applying the process variable at each point and noting the effect on the % O2.

For example: a compensation is needed for line pressure. A 4-20 mA line pressure sensor would be ranged over the compensation range. While the instrument reads a fixed % O2 value, a table is created (see example below) while varying the pressure at 20% of range intervals:

CALIBRATION

3 CALIBRATION

Factory Calibration:

The unit is factory calibrated at 5 points to maximize the accuracy over the desired range. The calibration generally includes Zero & Span points as well as 3 intermediate points. In the case of suppressed zero ranges then the lowest concentration will replace the Zero Point.

NOTE: Analyzers are calibrated in background gas suitable for the specific application. Customer's calibration gases must match the process gas. Please refer to Test Result Sheet or a Michell Instruments' representative

Field Calibration:

Like all process analyzers, the XTP601 will require periodic calibration. The frequency entirely depends on the location, application and accuracy requirements of the user. The typical calibration period is expected to be between 1 and 3 months with a Zero gas and a Span calibration on a monthly basis. The user should establish a calibration frequency to ensure that the reading is within the specifications required for the process.

XTP601 User’s Manual

NOTE: It is possible to switch off the Field Calibration and revert to the Factory Calibration. This can be useful for diagnostic purposes if the reading is not what is expected. The unit is delivered with a factory calibration and, as such, would not have any field calibration data. As soon as the first field calibration is performed, the field calibration setting is automatically switched on.

Preparation:

Go to Settings Page (see Section 2.7.1) and make a note of ON/OFF options for all settings. Re-set these options after calibration.

Sample Inlet Pressure:

• 0 to 4 barg (0 to 58 psig)

Sample Flow Rate:

GP1 & GP3 models: 100 to 500 ml/min (0.2 to 1.06 scfh)

EX1, EX3 & GP2 Models: 270 to 330ml/min (0.54 to 0.66 scfh)

There are 2 types of field calibration available.

22 97313 Issue 5, May 2018

XTP601 User’s Manual

3.1 1 Point Calibration

This is a single point offset overlaid on top of the factory calibration. It is designed to correct minor drift and minor changes during transit. This calibration makes the unit very accurate at the calibration point and improves accuracy throughout the range.

The calibration gas should be of a value that is within the main area of interest, i.e. if main points of interest for a 0-25% range instrument are around the 6% area then apply a calibration gas as close as possible, in the example below we used 6.5% O2.

Impedance mismatch can cause reflections of data as it passes down the cable and the reflections could be large enough to cause data errors.

NOTE 3: The maximum loop load resistance for mA outputs is 550Ω

NOTE 4: the mA outputs are powered with a 24V excitation voltage.
