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 should I use a capillary with a thermometer?

For gas-actuated or expansion thermometers, use a capillary in difficult-to-access locations and to bridge long distances. A flexible spiral sleeve or PVC coating can protect the thin measuring line.
