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), and also with refrigeration plants and compressors, 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 or vacuum 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 Unpacking the thermocouple and dismounting the protective transport tube
When unpacking the TC84 thermocouple, and also when removing the protective transport
tube, carry out the following steps:
1. Check the packaging for damage.
2. Open cardboard packaging.
3. Remove foam padding.
4. Lift out the TC84 thermocouple with two people.
5. Clamp the process flange in the vice
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 tube wall with the ceramic.
8. After loosening the clamping screws, carefully pull the protective transport tube off.
1) If no vice is available, we recommend disassembling on a workbench. The first person must support the connection
head and at the same time loosen the threaded connection as described in point 7. The second person, in the meantime,
supports the protective transport tube and pulls it off carefully.
