Application
The temperature sensors of the SITRANS TS product family are used for measuring temperatures in industrial plants.
Depending on the specifications, sensors can be combined with different connection heads, extension tubes, and process
connections. This makes the sensors suitable for a variety of process engineering applications, e.g. in the following sectors:
●Petrochemical industry
●Pharmaceuticals industry
●Biotechnology
●Foodstuffs

8A5E32897026-01, 09/2013
3.3
Functional principles
Two different measuring principles are used for measuring temperatures.
●With resistance thermometers, the temperature is measured as a change in resistance. Resistance thermometers
contain Pt100 sensor elements in accordance with IEC 60751.
●With thermocouples, the temperature is the change in voltage (Seebeck effect). The thermocouples are in accordance
with IEC 584/DIN EN 60584.

1. Define the measurement position.
2. Apply heat sink compound to the metallic part of the temperature sensor.
3. For standard version: halved pipe collar allows for quick and easy mounting on the pipe using two mounting screws.
For bracket version: mount on pipe using one mounting screw.
–If the pipe is not fully occupied by medium during installation, mount the temperature sensor on the underside of the
pipe.
4. Firmly tighten the mounting screws (4 Nm torque).
5. Mount the vibration protection and hand-tighten.
–You can remove the measuring insert only after you have released the Pt100 recessed grip screw(s).
–Do not twist the housing.
–Use Pt100 recessed grip screw for installation, only.
–Do not apply force to the transmitter housing (e. g. during opening/closing of lid).
–Because the locking plugs are fitted with internal gaskets they are only suited for ambient temperatures to 100 °C
(212 °F).

●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.
Procedure
1. Close the connection head. Fully screw on the cover for device versions with flameproof enclosures.
2. Connect the sensor integrated in the process to the power supply.

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
Recalibration procedure
Clamp-on version 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.
Block calibrators Use calibrator sleeves that have been adapted to the shape of the
Pt100 unit only.
