● You have connected the sensors correctly. For further details, see:
– Electrical connection of resistance thermometers (Page 18)
– Electrical connection of thermocouples (Page 18)
● Verify that the electrical connections are firmly tightened to the suitable torque.
● The following applies in particular with device versions with explosion protection:
– Verify whether the cable glands are appropriate for the process and are correctly tightened.
– The electrical data must match the specified ex-relevant values.
● All seals must be present, placed correctly and undamaged.

Service and maintenance

7.1 Service and maintenance
Recalibration
Temperature sensors are essentially maintenance-free. However, we recommend recalibration under the following
conditions:
● Processes with strong vibrations or changes in temperature.
● Food, pharma, biotechnology applications (annually), TS300 only.
● Processes that demand high measuring accuracy and safety.
Note
Recalibration intervals
Define the recalibration intervals for the specific process or plant. With constant operating temperatures and a low load,
the reference values are as follows:
● < 2 years at temperatures up to 400 °C
● < 5 years at temperatures up to 200 °C
Recalibration of SITRANS TS300
Description
Clamp-on version
Block calibrators

Recalibration procedure
Do not disconnect the pipe sleeve from the pipe - leave the
measuring position unchanged for reproducible measurement.
It is not necessary to disconnect the power supply to perform
calibration.
Loosen recessed grip screw(s) to remove the Pt100 connector or
housing and unscrew the measuring insert from the pipe collar.
Use calibrator sleeves that have been adapted to the shape of the
Pt100 unit only.
