DEVICE DESCRIPTION 2

2.2 Device description

2.2.1 Design of industrial thermometers for advanced requirements

INFORMATION!

In this documentation, the name "Industrial thermometer for advanced requirements" refers to thermometer assemblies with multipart, welded thermowells as well as those with one-piece bar stock thermowells.

Figure 2-1: Design of an industrial thermometer for advanced requirements

1 Connection head cover 2 Measuring insert 3 Cable gland M20 x 1.5 (only available if the process connection has the dimensions M24 x 1.5, otherwise there is a blind

plug here instead)

4 Neck tube 5 Connection head

All thermometers for advanced requirements consist of a thermowell with process connection, a neck tube and a connection head. The connection head and the thermowell are largely thermally decoupled by way of the neck tube. The neck tubes for thermometers with advanced requirements are available with two different thread types:

• As per DIN: M24 x 1.5 mm

• As per ASME/ANSI: ½"NPT

The connection head is screwed onto the neck tube using the thread. The M24 x 1.5 thread makes it possible to align the connection head so that the cable gland always faces in the desired direction (during assembly, the connection head is aligned first before screwing in the thread

using hex nut). In contrast, the alignment of the connection head with ½" NPT threads is only

possible to a limited extent, depending on the type of neck tube.

You can insert either a measuring insert with RTD (OPTITEMP TR 100) or with thermocouple (OPTITEMP TC 100) into the thermometer assembly. Both measuring inserts are available in three different versions (for more information see refer to

measuring insert length

(for more information see refer to

2 DEVICE DESCRIPTION

2.2.2 Types of connection heads

A connection head protects the terminals and the temperature transmitter from environmental effects (e. g. dirt or dust). The cable gland for the connection head on the industrial thermometer for advanced requirements depends on the process connection for the connection head

(M20 x 1.5 for process connections with the dimensions M24 x 1.5 and ½" NPT for all process connections with ½" NPT threads, for more information see refer to

There are oil-resistant rubber seals on the covers of all connection heads (can be used up to

100°C / 212°F ambient temperature). The connection heads are available in the following

materials:

• Die-cast aluminium for standard applications (Types: BA, BUZ-T/S/H/HW, BGK and AXD). The

surface of these connection heads features a 70µm thick powder coating made of polyester.

• Stainless steel (type BVA), especially for the pharmaceutical and food and beverage industries

• Plastic (type BBK)

The type "BUZ-HW" is the only connection head with an integrated, head-mounted display fed by the 4...20 mA current loop.

2.2.3 Measuring insert designs and measuring insert length

INFORMATION!

The versions, dimensions and other construction features of the measuring inserts are standardised in DIN 43735.

The replaceable measuring insert contains the temperature sensor, which may be either a Pt100 RTD or a thermocouple. The measuring insert is pushed through the open connection head into the thermometer assembly and attached using two spring loaded M4 screws (this guarantees that the tip of the measuring insert is in constant contact with the bottom of the thermowell). The following versions of measuring insert are available:

OPTITEMP TRA/TCA PLUS

Figure 2-2: Available measuring insert versions

1 Measuring insert with flying wires 2 Measuring insert with ceramic terminal block 3 Measuring insert with head-mounted transmitter

www.krohne.com 01/2012 - 4000630301 - MA OPTITEMP TRA/TCA Plus R01

Page 15

OPTITEMP TRA/TCA PLUS

One distinguishing dimension of the measuring insert is its length. The length is measured from the bottom edge of the base to the tip of the immersion tube ("a" in the drawing below):

Figure 2-3: Measuring insert length

The selection of the right measuring insert depends on the conditions of use:

• A measuring insert with a thermocouple is better suited to heavy thermal or mechanical loads.

• When increased accuracy is required, a measuring insert with a resistance thermometer is

better suited for temperatures up to +500°C / +932°F and in exceptional cases up to +600°C/ +1112°F.

DEVICE DESCRIPTION 2

INFORMATION!

Consult the handbook "OPTITEMP TR/TC 100" for more detailed information on the measuring inserts.

2.2.4 Types of temperature transmitters

Electrical thermometers have just one, weak, interference-prone output signal. If this signal has to travel a great distance or if a standard signal of 4...20 mA is required, use of a temperature transmitter is recommended:

INFORMATION!

The manufacturer cannot make any general statement as to the distance from which the use of a temperature transmitter is necessary as it depends on the specific interference associated with the installation site. The operator alone is responsible for this decision.

There are two types of temperature transmitters:

• Head-mounted transmitter: Located on the measuring insert and thus in the connection head of the thermometer during operation, recognisable by the "C" in the product name (e.g.TT10C)

• Rail-mounted transmitter: Located in the control cabinet or field housing, recognisable by the "R" in the product name (e. g. TT 11 R); they are usually used when the temperature in the connection head does not allow for the use of a head-mounted transmitter

www.krohne.com01/2012 - 4000630301 - MA OPTITEMP TRA/TCA Plus R01

Page 16

2 DEVICE DESCRIPTION

Figure 2-4: Example of a head-mounted transmitter

OPTITEMP TRA/TCA PLUS

Figure 2-5: Example of a rail-mounted transmitter

Head-mounted and rail-mounted transmitters both convert the temperature sensor's small signal into a standardised output signal of 4...20 mA, not susceptible to interference, or into a digital signal. The output signal depends on the type of temperature transmitter. The following three 2-wire technology options are currently available:

• 4...20 mA

• 4...20 mA with HART

• Profibus-PA

You can parameterise almost any temperature transmitter using a PC and a computer program. The only exceptions are the TT 10 C/R and TT 11 C/R versions, whose measuring ranges must be set using solder bridges. The following temperature transmitters are currently available:

INFORMATION!

Consult the relevant transmitter handbook for more detailed information on the temperature transmitters.

2.2.5 Neck tubes

The neck tube connects the process connection (i.e. screw socket or flange) to the connection head. Its function is to largely thermally decouple the connection head so that it and any existing temperature transmitter do not heat up too much. Depending on both the standard and the version of the thermowell, there are different threads:

Page 18

2 DEVICE DESCRIPTION

The neck tubes for industrial thermometers for advanced requirements are made of stainless steel.

INFORMATION!

The neck tube material may differ from the thermowell material.

The standard neck tube length of a DIN neck tube is 165 mm / 6.5", that of a NUN connection

with ½" NPT thread is 152 mm / 6". Other neck tube lengths are available on request.

2.2.6 Thermowells and thermowell tips

The thermowell is designed to prevent external loads (e. g. static pressure, flowing and aggressive media) from damaging the measuring insert. As a rule, thermowells are made of the same material as the system in which the measuring is done. In terms of the material and design, we can distinguish between two types of thermowells:

• Multipart, welded thermowells

• One-piece bar stock thermowells

OPTITEMP TRA/TCA PLUS

This handbook covers thermometers for advanced requirements such as high pressure and high flow velocities. For this reason, one-piece thermowells manufactured using bar stock are used in addition to multipart welded thermowells.

INFORMATION!

The manufacturer checks all of the thermowells for leaks. An optional certified pressure test is available for a fee.

Thermowells and thermowell tips in different versions are manufactured for the industrial thermometers for advanced requirements. For more information refer to

Diameter, wall thickness, tips

Both the reduced and the conical tip feature a shorter response time than a straight thermowell. However, compared to the reduced tip, the conical tip withstands higher pressures.

2.3 Process connections and areas of application

2.3.1 Weld-in thermometer

DEVICE DESCRIPTION 2

standard

Weld-in thermometers for advanced requirements are always the first choice when you want to measure temperatures in quickly flowing product under high pressure. Compared to threaded thermometers for advanced requirements, weld-in thermometers are more resilient as they are not weakened by the notch effect of a thread on the joint.

A typical area of application for weld-in thermometers with advanced requirements is the measurement of temperature in process vapour lines and cooling water lines, especially in power plants.

2.3.2 Threaded thermometer

Threaded thermometers with separate neck tubes are particularly well suited to measuring tasks in process technology or machine building and plant engineering. In this case, screwing into the pipelines and tanks is the most common process adaption.

The neck tube increases the distance between the process connection and the connection head so that the latter does not overheat. It also makes it possible to install connection heads outside of the insulation of pipelines and tanks.

The threaded thermometers for advanced requirements are offered with three different thermowell shapes forms which are similar to or comply with DIN and ASME standards. These include a straight thermowell, a conical thermowell and a reduced thermowell. G or NPT thread variants are available.

Page 20

2 DEVICE DESCRIPTION

2.3.3 Flange thermometer

All of the flange thermometers for advanced requirements available from the manufacturer feature a separate neck tube to thermally decouple the process connection and connection head. They are typically used in the mid and upper temperature range in industrial applications (up

to +600°C / +1112°F).

Flange thermometers for advanced requirements are predominantly suited to measuring the temperature in the chemical and petrochemical industries (particularly for pipelines, tanks and reactors). This area of application opens up because optional coating of the surface is possible. According to the requirements for chemical resistance, the manufacturer can coat the flange thermometer with Teflon, PTFE or a customer-specific material.

When it comes to flanges, you can choose between DIN and ASME flanges. The surface roughness of the flange raised face is R

= 3.2...6.3 μm (ASME flanges).

As with the threaded thermometers for advanced requirements, the flange thermometers for advanced requirements also give you the choice between different thermowell forms which are similar to or comply with valid DIN and ASME standards. Also included are a straight thermowell, a conical thermowell and a reduced thermowell.

OPTITEMP TRA/TCA PLUS

3.4 Proper installation

CAUTION!

Take the following points into consideration prior to installing the thermometer:

•

The dimensions of the thermowell (length, diameter, wall thickness, type of tip) comply with the requirements of the measuring point. The mechanical load as a result of flowing media, vibration and resonances is the focus here. In addition, incorrect dimensions can lead to measurement errors.

•

The thermowell is sufficiently resistant to chemically aggressive media (refer to the generally accessible corrosion tables). Otherwise, corrosion may occur or the medium may penetrate into the thermowell. When in doubt, select a thermowell made from the same material as your system.

3.4.1 Possible installations

Installations include the parameters "installation site", "installation angle" and "insertion length". Depending on the space available and the diameter of the pipe, three installations are recommended for pipes with flowing product:

INSTALLATION 3

• Small pipe diameter: Installation directly against the direction of flow in a bend in the pipe (1).

• Small pipe diameter: Installation diagonally against the direction of flow, if a bend in the pipe is available (2).

• Large pipe diameter: Vertical installation, if flow-induced periodic vortex shedding does not cause the thermometer to vibrate in its resonance frequency (3).

Figure 3-1: Recommended installations

Permitted insertion length of the thermowell or measuring insert

Permitted insertion length of the thermowell or measuring insertPermitted insertion length of the thermowell or measuring insert

The "insertion length" of the thermowell or measuring insert refers to the distance from the seal of the process connection (for G threads), two-thirds of the thread height (for NPT threads) or the bottom of the flange (for flange thermometers) to the tip of the thermowell or sheath. This length determines how far the sensor projects into the measured medium.

www.krohne.com01/2012 - 4000630301 - MA OPTITEMP TRA/TCA Plus R01

Page 28

3 INSTALLATION

To avoid measurement errors, ensure that the insertion length ("b" in the drawing below) meets the following requirements:

• Insertion length = 10...15 x thermowell diameter, but at least 100 mm / 3.94" (shorter insertion lengths are possible but they impair measuring accuracy).

• Tubes with Ø < 300 mm / 11.8": thermowell tip should project past the middle of the pipe is possible, if the flow velocity of the product allows it.

OPTITEMP TRA/TCA PLUS

Figure 3-2: Permitted insertion length

INFORMATION!

For more information on the maximum insertion length, please refer to the subsection "Typical load types".

3.4.2 Other installation requirements

DANGER!

When a seal is damaged or incorrect, the medium may leak out, causing material damage or bodily harm! It is the sole responsibility of the operator to select the right seal.

• A well-insulated pipeline or tank around the measuring point reduces the heat transfer and the distorting influence of the ambient temperature.

• To avoid measurement errors caused by poor heat transfer, the measuring insert must always be in contact with the bottom of the thermowell (this is normally guaranteed by the spring-loaded version of the measuring insert).

• Choosing the right gasket for the process connection depends on the process conditions; the manufacturer can thus only give the general recommendation that the gasket must comply with the individual requirements of the measuring point (e.g. pressure, temperature, chemically aggressive media).

Page 29

OPTITEMP TRA/TCA PLUS

3.5 Load limits

The load limits of industrial thermometers depend on several factors:

• Dimensions and design of the thermowell (especially the insertion length and diameter)

• Thermowell material

• Mechanical conditions the thermowell is subject to due to the measured medium (pressure,

temperature, flow velocity, viscosity, density)

• Sealable pressure of the process connection

• Vibration load

INFORMATION!

The "sealable pressure" is the maximum pressure the process connection can seal against.

The sheer number of factors at play illustrates the difficulty in making universally valid statements about the load limits. The diagrams in the next subsection serve as an initial assessment.

INSTALLATION 3

3.5.1 Typical load types

DANGER!

To prevent destruction or damage, never operate the thermometer outside of its permissible mechanical, thermal or chemical limits. For further information refer to the rest of this section and the "Technical data" section.

DANGER!

The information in this subsection is informative only and does not reflect the vibration load caused by flow-induced eddy shedding and the resulting vibration. If necessary, prior to purchasing and installing an industrial thermometerfor advanced requirements, have a specific strength calculation performed (e. g. as per DITTRICH or MURDOCK, ASME PTC 19,3TW-2010). For further information contact the manufacturer.

INFORMATION!

The manufacturer can provide an optional strength calculation for a fee.

3 INSTALLATION

3.5.2 Vibration load

CAUTION!

Permanently operating the thermowell in its natural resonance can quickly damage or destroy the thermometer! So, prior to installation, ensure that this does not happen and select a thermowell with a different length, a different diameter or another material if necessary.

All thermometers that feature a thermowell and neck tube and are attached to the process connection have two components that can vibrate: the thermowell and the connection head with the neck tube. That is why the terms "thermowell resonance" and "head resonance" are commonly heard.

A thermowell surrounded by the measured medium is a body behind which vortices periodically are released ("Kármán vortex street"). If the frequency of the vortex detachment is equal to the resonance frequency of the thermowell, it starts to vibrate. If this happens for a short period of time, such as when starting up the system and the frequency of the vortex detachment passes through the resonance range of the thermowell, there is generally no damage is caused. The opposite is true, however, if the vibrations remain permanently in the resonance range.

3.5.3 Temperature load

OPTITEMP TRA/TCA PLUS

For this reason, all of the industrial thermometers for advanced requirements feature a neck tube. It causes extensive thermal decoupling and can prevent the connection head and the temperature transmitter from overheating at high process temperatures.

CAUTION!

When the temperature is too high, the connection head and the components found in it (e. g. temperature transmitter or display) can be damaged or destroyed! It is your responsibility as the operator to ensure that the connection head does not get too hot. If this does happen, select another installation site or lengthen the neck tube or, with insertion-type thermometers, increase the distance between the connection head and the process connection.

CAUTION!

Sometimes even a neck tube cannot prevent the maximum permissible temperature in the connection head from being exceeded! It does cause extensive thermal decoupling of the connection head but you still have to always take into consideration the installation situation as well as the ambient and process temperatures!

The following diagram will aid in the selection of the right neck tube length and shows how the process temperature and the neck tube length impact the temperature of the connection head:

CAUTION!

The diagram only shows the amount by which the temperature of the connection head increases. To determine the actual temperature of the connection head you must add the ambient temperature to it in a second step!

3.6 Installation notes on the individual device classes

3.6.1 Weld-in thermometer

Compared to other types of fastening, welding in thermometers allows for higher process pressures and flow velocities. Weld-in thermometers can be installed in two different ways:

• Welded in directly: possible in pipes and tanks with a wall thickness ≥20 mm / 0.79"

• Welded in using a welded sleeve: pipes and tanks with a wall thickness < 20 mm / 0.79"

require welding of a sleeve, into which the thermowell is then welded.

The following drawing shows a weld-in sleeve suitable for the TRA/TCA-T30 version:

OPTITEMP TRA/TCA PLUS

5 OPERATION

5.1 Start-up

CAUTION!

Double check the following things prior to starting up an industrial thermometer in order to avoid measuring errors as well as damage to or the destruction of the thermometer:

•

Ensure that the thermowells have been properly installed according to the manufacturer's instructions.

•

Ensure that the process connection has been successfully tested for leaks.

•

Ensure that the measuring insert sits firmly on the bottom of the thermowell.

•

Ensure that the measuring insert has been properly electrically connected according to the manufacturer's instructions (refer to measuring insert handbook).

CAUTION!

When operating the transmitters and the display in the BUZ-HW connection head, always refer to the technical documentation of these devices.

5.2 Normal operation

OPTITEMP TRA/TCA PLUS

During the course of normal operation, it is not necessary to make any adjustments to the thermometer, measuring insert, temperature transmitter or temperature indicator.

WARNING!

Never touch the thermowell, neck tube or connection head in operation without protective gloves! These components can become very hot during operation and cause burns.

5.3 Faults and damage: reason and remedies

INFORMATION!

The most probable cause of a fault is the measuring insert itself and its electronic components (see the handbook for measuring inserts, subsection "Faults: Reasons and Remedies"). The following issues come into question here:

•

Short circuit or open circuit

•

Insulation resistance too low

•

Ageing

•

Wrong thermocouple wire or compensating line

In addition, the following faults and damage may occur:

Liquid on the process connection

A damaged or incorrect seal can lead to a leak at the process connection. Should this occur, replace the seal and ensure that the new one meets the individual requirements of the measuring point (pressure, temperature, chemically aggressive media). It is the sole responsibility of the operator of the device to select the right seal.

www.krohne.com 01/2012 - 4000630301 - MA OPTITEMP TRA/TCA Plus R01

Page 39

OPTITEMP TRA/TCA PLUS

Temperature indication too high or too low

When reference measurements result in an incorrect temperature indication, three causes come into question:

• Severe heat transfer caused by too short insertion length of thermowell or measuring insert: the thermometer indicates a temperature that is too low when it is above the ambient temperature and one that is too high when it is below the ambient temperature.

• Severe heat transfer via the process connection, the pipeline or the tank wall due to a lack of insulation.

• Incorrect thermowell dimensions (diameter, wall thickness).

To keep the heat transfer to a minimum, either increase the insertion length of the thermometer or improve the insulation of the measuring point.

Slow response to changes in temperature

If the measuring insert is not resting firmly on the bottom of the thermowell, the response to any changes in temperature may be slowed. So, ensure that the measuring insert touches the bottom of the thermowell using the spring-loaded mounting. If the thermometer is to react to changes in temperature as quickly as possible, thermowells with a tapered or reduced tip are recommended.

OPERATION 5

Damage to the thermowell and penetrating liquid

If the thermowell is not sufficiently resistant to chemically aggressive media, corrosion may occur and the measured medium may penetrate. In case of doubt, choose a thermowell made of the same material as the pipe or tank in which the medium is located.

Breaks or tears

It is possible for breaks or tears to occur due to the force of the media flowing against the thermowell. It is also possible for vibrations in the resonance range to damage or destroy the thermowell. Superimposition of the two causes or a combination of insufficient mechanical and chemical resistance is also possible. The following are starting points for troubleshooting:

• Selection of a thermowell with different dimensions

• Change in neck tube length at critical head resonances

• Selection of a different installation site

6 SERVICE

6.1 Replacing the electronics

When it comes to industrial thermometers for advanced requirements, it is only possible to replace an electronic component if there is a temperature transmitter or, if applicable, a headmounted display. Consult the handbook for the temperature transmitter or, if applicable, the head-mounted display to learn what you need to take into consideration when replacing the electronics.

6.2 Cleaning and maintenance

As a rule, the industrial thermometers for advanced requirements require no cleaning or maintenance. However, depending on the conditions of use and the thermal and mechanical load, they can age. This is true of both measuring inserts with Pt100 RTDs and measuring inserts with thermocouples.

As a result of the ageing process, the characteristics ("characteristic curve") can change. That means that the relationship between the electrical resistance (measuring insert with Pt100 RTD) or the thermovoltage (measuring insert with thermocouple) and the temperature changes. In this case, calibration shows whether any deviations in measurement values are still within permissible tolerances.

7.1 Measuring principle

All of the thermometers described here belong to the class known as "contact thermometers". Unlike "radiation thermometers", these thermometers come into direct contact with the medium whose temperature they are to measure.

The type of measuring principle depends on the measuring insert sensor that you combine with the transmitter. Two different sensor types are available. Their respective measuring principles are described in the following subsections.

7.1.1 Resistance thermometer

The measuring insert with a resistance thermometer features a temperature-sensitive sensor

made from a platinum RTD, whose value at 0°C / +32°F is 100 Ω. That is where the name "Pt100"

comes from.

It is generally valid that the electric resistance of metals increases according to a mathematical function as the temperature rises. This effect is taken advantage of by resistance thermometers to measure temperature. The "Pt100" thermometer features a measuring resistance with defined characteristics, standardised in IEC 60751. The same is true for the tolerances. The

average temperature coefficient of a Pt100 is 3.85 x 10

+32...+212°F.

TECHNICAL DATA 7

-3K-1

in the range from 0...+100°C/

During operation, a constant current I (≤ 1 mA) flows through the Pt100 RTD, which brings about a voltage drop U. The resistance R is calculated using Ohm's Law (R=U/I). As the voltage drop U

at 0°C / +32°F is 100 mV, the resulting resistance of the Pt100 thermometer is 100 Ω (100 mV /

1 mA = 100 Ω).

7.1.2 Thermocouples

The thermocouple features two electric conductors made from different metals, connected at one end. Each free end is connected to a compensation cable which is then connected to a millivolt meter. This circuitry forms a "thermal circuit". The point at which the two electric conductors connect is called the measuring point and the point at which the compensation cables connect to the conductors of the millivolt meter is called the cold junction.

If the measuring point of this thermal circuit is heated up, a small electrical voltage (thermal voltage) can be measured. If, however, the measuring point and the cold junction are at the same temperature, no thermoelectric voltage is generated. The degree of thermoelectric voltage, also known as electromotive force (EMF), depends on the thermocouple material and the extent of the temperature difference between the measuring point and the cold junction. It can be measured using the millivolt meter with no auxiliary power.

Simply put, the thermocouple behaves like a battery, the voltage of which also increases as the temperature rises.

INFORMATION!

The characteristic curves and tolerances of commercially available thermocouples are standardised in IEC 60584.

7 TECHNICAL DATA

7.4 Measuring accuracy

The measuring accuracy depends largely on the following factors:

• The version of the measuring insert (type of sensor, type of circuit, measuring range).

• The correct dimensions (diameter, wall thickness) and insertion length of the thermowell for

good thermal coupling to the process temperature (insufficient insertion depth often results in measurement errors).

• The type of temperature transmitter used.

INFORMATION!

Please consult the appropriate handbook for further information regarding the accuracy of the measuring inserts and the temperature transmitters.

With the exception of the TT 60 C/R version, all of the temperature transmitters generate an analogue output signal. For this reason, the following table indicates the measuring accuracy of most of the transmitters as a percentage of the measuring range:

7.6 Measuring range and permitted load

DANGER!

To prevent fatal injuries or damage, never operate the thermometer outside of its permissible mechanical, thermal or chemical limits. For further information refer to the rest of this section and the "Technical data" section.

DANGER!

CAUTION!

To prevent destruction or damage, only operate a thermometer without a thermowell in the range of 0.8...1.2 bara / 11.6...17.4 psia.

INFORMATION!

The manufacturer can provide an optional strength calculation for a fee.

OPTITEMP TRA/TCA PLUS

Temperatures that can be measured with an industrial thermometer depend largely on the load of the thermometer. Load limits are defined through a variety of factors (see the subsection "Load limits" in the "Installation" section). For this reason, the manufacturer cannot make any universally valid statements about the measuring range and permissible load.

INFORMATION!

The thermowell operating limits specified below refer to a flow of air of 40 m/s or 131.2 ft/s or a flow of water or vapour of 5 m/s or 16.4 ft/s.

The temperatures specified in the following tables are valid only for thermowells and immersion tubes that do not project into flowing media or media under pressure. The maximum permissible temperature is reduced under load.

DANGER!

If you are unsure as to whether the device can withstand the loads of the process when using an insertion-type thermometer without thermowell, have a separate strength calculation done (e.g. per DITTRICH or MURDOCK, ASME PTC 10.9-TW)! For further information contact the manufacturer.

7.8 Sensor response times

Thermometer response times are generally indicated as "50% time" (t05) and "90% time" (t09). "50% time" refers to the time needed for a thermometer signal to achieve 50% of its end value in

the face of erratic temperature changes (this applies analogously to "90% time").

INFORMATION!

You can find more information about response times in VDI 3522.
