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
Cross-check scope of delivery with delivery note.

Information
... points out useful tips, recommendations and information for efficient and
trouble-free operation.
3.2 Intended use
The thermometers described here are suitable for temperature measurement in industrial
applications.
These thermometers are intended for direct installation in the process without the use of an
additional protection tube (exception: primary protection tube, model TW83).
The models TC82, TC83 Calitum®and TC84 thermometers prevent toxic gases from
escaping from the process in the event of damage to the protection tube, by means of
special, multiple sealing systems.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
3.3 Responsibility of the operator
The system operator is responsible for selecting the thermometer or protection tube, and
for the selection of their materials, so as to guarantee their safe operation within the plant
or machine.When preparing a quote, WIKA can only give recommendations which are
based on our experience in similar applications.
The safety instructions within these operating instructions, as well as the safety, accident
prevention and environmental protection regulations for the application area must be
maintained.
The operator is obliged to maintain the product label in a legible condition.

3.4 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to property.
▶
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualifications described
below.
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based
on their technical training, knowledge of measurement and control technology and on
their experience and knowledge of country-specific regulations, current standards and
directives, are capable of carrying out the work described and independently recognising
potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive or
toxic media.
3.5 Personal protective equipment
The personal protective equipment is designed to protect the skilled personnel from
hazards that could impair their safety or health during work.When carrying out the various
tasks on and with the instrument, the skilled personnel must wear personal protective
equipment (e.g. gas detector, harness, etc.).
Follow the instructions displayed in the work area regarding personal protective
equipment!
The requisite personal protective equipment must be provided by the operating company.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2 “Packaging
and storage”.
▶
If the shock indicator has been triggered, acceptance of the goods from the
transport company is only permissible with reservations and must be noted
on the transport company's documents. Check the shock indicator before
opening the packaging or removing the instruments. If the shock indicator
has been triggered, inform your WIKA contact person. We recommend
photographic documentation of the packaging and the instruments.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.

4.2 Packaging and storage
Do not remove packaging until just before mounting.When removing the instrument from
the packaging, make sure that the instrument rests on, for example, the table in such a
way that fragile materials and components are not loaded. Depending on the size of the
assembly, two people may be required to handle it.
Special instructions for unpacking the model TC84 thermocouple and dismounting
the protective transport tube
1. Check the packaging for damage.
2. Open cardboard packaging.
3. Remove foam padding.
4. Lift out the model TC84 thermocouple with two people.
5. Clamp the process flange in the vice 1) using suitable protective jaws.
6. Remove the additional protection from between the ceramic tube and the protective
transport tube.
7. Carefully and alternately loosen the three clamping screws on the protective transport
tube in order to prevent any tilting of the protective transport tube. At the same time, a
second person must observe the opening of the protective transport tube at the lower
end in order to prevent any contact of the pipe wall with the ceramic.
8. After loosening the clamping screws, carefully pull the protective transport tube off.
Store the Styrofoam packaging as well as the protective transport tube of the probe for any
return transport (repair option).

WIKA operating instructions models TC80, TC82, TC83, TC8410
Store the instrument in its original packaging in a location that fulfils the conditions listed
above. If the original packaging is not available, pack and store the instrument as described
below:
1. Place the instrument, along with the shock-absorbent material, in the packaging.
2. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
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.
