2. Design and function
2.1 Description
Thermocouples are used for temperature measurement in industrial applications such as
heat-treatment furnaces, sulphur recovery plant or gas reactors.
This document describes standard versions of instruments. For applications in hazardous
areas special instrument designs are required.
For further information for operation in hazardous areas, see the additional information for the
corresponding ignition protection type (separate document).
The model TC80 thermometer corresponds to DIN EN 50446 and uses metallic and/or
ceramic protection tube materials. The model TC82 protects the thermocouple using one or
two ceramic protection tubes or a thermowell made from silicon carbide. For both models,
the possibility exists of optionally increasing the service life through the use of gas purging.
The TC83 Calitum®and TC84 thermometers, in addition to the ceramic exterior protection
tube, use a further monocrystalline sapphire protection tube, which makes purging
unnecessary.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
2.2 Scope of delivery

5. Commissioning, operation
WARNING!
Damage to the measuring instrument by operation outside the upper or
lower limits of the operating temperature
Failure to observe the permissible operating temperature, also taking into
account convection and radiation, can even cause damage to the thermometer
during mounting.
▶
The upper and lower limits of the specified operating temperature range
must not be exceeded.
WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), there is a danger of physical injuries and damage to property
and the environment.
Should a failure occur, aggressive media with extremely high temperature and
under high pressure may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment.
5.1 Mechanical mounting
5.1.1 Mounting instructions for electrical thermometers with ceramic protection tube
Ceramic protection tube materials withstand changes in temperature only to a limited
extent. A temperature shock can therefore easily result in stress cracks and consequently
in damage to the protection tube.
Insert thermocouples with ceramic or sapphire protection tubes into the hot process slowly.
In accordance with DIN 43724, an insertion speed of 1 cm/min [0.375 in/min] is
recommended for protection tubes with a diameter of 25/26 mm [approx. 1 in]. For smaller
diameters of 10/15 mm [0.375/0.625 in], this can be increased to 50 cm/min [20 in/min]. As
a basic principle, higher process temperatures require a lower insertion speed.

EN
5. Commissioning, operation
14486177.01 07/2021 EN/DE
WIKA operating instructions models TC80, TC82, TC83, TC84 11
In addition to the protection from thermal stress, ceramic protection tubes must also be
protected from mechanical loads. The reason for these harmful stresses are, for example,
bending forces in the case of a horizontal mounting position. As a consequence, an
additional support should be provided in the case of a horizontal mounting position,
depending on the diameter and the design, and for higher nominal lengths. Furthermore,
avoid shock loads during installation, as these can also damage the thermocouple.
The advice regarding the problems caused by bending forces also applies, in principle, to
metallic protection tubes, particularly for insertion lengths > 500 mm [> 20 in]. With process
temperatures > 1,200 °C [> 2,192 °F], a vertical installation is always favoured.
In order to counteract the heat reflux in the nozzle, we offer suitable accessories (sealing
washers).
▶
see chapter 10 “Accessories”
The flange dimensions must match those of the mating flange on the process side.The
sealings used must be suitable for the process and the flange geometries (consult the
delivery note). When mounting, depending on the sealing used, use the appropriate
tightening torques and tools (e.g. torque spanner).
Although ceramic protection tubes are considered gas-tight in accordance with
DIN EN 50446, diffusion of gas from the process into the sensor cannot be ruled out,
particularly at high temperatures. As a result of this, the resistance of the thermocouple
material to the medium should be explicitly considered. The responsibility for the
choice of materials for the safe function of the thermometer/protection tube within the
plant/machinery is the responsibility of the customer/operator. WIKA can only give
recommendations which are based on our experience in similar applications.
Due to the high thermal, chemical, and mechanical loads to which ceramic and sapphire
protection tubes are subjected during operation, a general indication regarding the
service life can only be given to a limited extent.This is particularly valid for applications in
high-load processes, such as gasification reactors or sulphur recovery plant. According to
this, the process-related parts of the thermocouples are wear parts which are not covered
by the warranty.
Thermometer with purge connection
For thermometers with purge connection the following basic settings are recommended:
Pressure of purge gas: 0.25 ... 0.35 bar [3.6 ... 5.1 psi] over maximum process pressure
Flow rate: approx. 10 ... 12 LPH
Purge gas: Nitrogen

Depending on the process an adjustment of given values can be required.The sole
responsibility for this rests with the end user.
5.2 Electrical mounting
Using a transmitter/digital display (option):
Observe the contents of the operating instructions for the transmitter/digital display (see
scope of delivery).
Cable glands
Requirements for meeting ingress protection:
■
Only use cable glands within their indicated clamping area (cable diameter suitable for
the cable gland).
■
Do not use the lower clamping area with very soft cable types.
■
Only use round cables (if necessary, slightly oval in cross-section).
■
Do not twist the cable.
■
Repeated opening/closing is possible; however only if necessary, as it might have a
detrimental effect on the ingress protection
■
For cable with a pronounced cold-flow behaviour the gland must be fully tightened.
5.3 Electrical connection
CAUTION!
Danger of short-circuit
Damage to cables, wires and connection points can lead to malfunction of
the instrument.
▶
Avoid damaging the cables and wires. Fine-stranded leads with bare ends
must be finished with end splices.

For contact details see chapter 1 “General information” or the back page of
the operating instructions.
7.1 Maintenance
The thermometers described here are maintenance-free.
Repairs must only be carried out by the manufacturer.
Repair option for model TC84
The construction of the thermocouple is designed so that a defect in an element
following the removal from the reactor can be repaired and reconditioned economically in
comparison to the cost of a new thermocouple.
For this, the complete defective element must be sent back to the manufacturer. Here, the
metal connection housing with flange will be cleaned, surface coating renewed, and also
all sealing faces freshly smoothed. Then, the connection housing will be completed with a
new protection tube measuring insert and a combined pressure testing undertaken.
Note:
It is not possible to deliver individual measuring inserts that will be fitted into the element
case at the customer site since the combined pressure testing by the supplier is a
constituent element of the guarantees.
