3.2 Mounting the SITRANS TS500
Requirement
The device is suitable for the process with regard to the process connection, media compatibility,
temperature resistance and measuring range. See section Technical data (Page 39).
Procedure
1. You prevent faults caused by the heat dissipation in non-representative arrangements by
observing the following basic rules:
2. Select an optimal immersion depth. Estimate the immersion depth using the formulas listed
in Estimation of immersion depth (Page 52).
If permitted by the 󹪞ow velocity, a sensor arrangement between one-third and one-half of
the conduit diameter is recommended.
3. If the process load at the sensor pocket permits the exposition, select a measurement
location with greater 󹪞ow velocity.
4. Ensure that there is su󹪟cient thermal insulation of the external components of the
thermometer.
5. Ensure that external parts have small surfaces.
6. Select the optimum mounting position for the process in question.

8. Observe the torques required between device extension and conduit Torques between
device extension and conduit (Page 52).
– If customized adaptations are necessary (only M24 connectors), note the required
torques between the device head and extension as speci󹪝ed in Torques between device
head and extension (Page 52).
– When mounting a SITRANS TS500 in full material design type 4 without 󹪞ange (only
Europe portfolio 7MC752..) of the device extension at the conduit, observe the
required Torques between device extension and conduit (Page 52).
3.3 Mounting SITRANS TS300 in clamp-on design
Note
Measuring position
Only install on round pipes. Avoid an installation close to pipe elbows, sliders, valves, etc.
1. Determine the measuring position on the pipe.
2. Apply the thermal paste on the metal part of the temperature sensor.
3. For the standard design: Install the two sleeving parts to the pipe using two 󹪝xing screws.
For the clamp design: Mount the SITRANS TS300 using a 󹪝xing screw.
– If the process medium does not 󹪞ow through the full cross-section of the pipe, mount the
temperature sensor on the bottom of the pipe.
