2.2.4 Housing
The housing connects the process connection (i.e. screw socket or flange) to the electrical
contact. Its function is to thermally decouple the connection and transmitter so the ambient
temperature doesn't exceed the permissible limits.
The materials of the housing and the thermowell are identical.
2.2.5 Thermowells
The thermowell is designed to prevent external loads (e. g. static pressure, flowing and
aggressive media) from damaging the sensor element. As a rule, the thermowell is made of the
same material as the system in which the measuring is done. The thermowell is built up from
multiple part and welded together.
INFORMATION!
Consult the relevant transmitter handbook for more detailed information on the rail mountesd
temperature transmitters.
