Thermometers with switch contacts

Display and monitor limit values

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.

When a temperature sensor is placed inside a thermowell or protection tube, what are the factors that influence response times?

The thinner the thermowell or protection tube, and the less air space there is between the sensor and the cylinder’s interior walls, the faster the response time. However, thin walls make the thermowell or protection tube less able to withstand agg ...
