Thermometers with switch contacts

Wherever the process temperature has to be indicated locally and, at the same time, limit values must be monitored, thermometers with switch contacts find their application. The switch contacts make or break the circuit dependent upon the pointer position of the indicating measuring instrument. If the reading is significantly above or below a set value, they trigger an alarm, hence also the term “alarm contact”. The instruments are also suitable for starting, stopping or switching processes.

FAQ

How high is the permissible pressure loading for thermowells?

In the Appendix to DIN 43772 are loading diagrams, from which, depending on temperature and medium, can be taken, the maximum allowable pressure load for the different geometries. If the conduit geometry does not correspond to DIN 43772, individual calculations can ... More

What is the maximum insertion length for a thermowell?

For multi-piece thermowells, the maximum length is limited by the manufactured lengths of the tubes, which is about 5-6 meters.  One piece thermowells are made of solid material and limited by the production length of the drill hole, which, for each product is ... More
