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

Why is liquid damping an advantage with negative ambient temperatures?

Since with unfilled instruments, there can be a possible build-up of condensing water, the window can become steamed up. This is not possible in filled instruments.

Why can't the shaft of the bimetal thermometers be manufactured longer than 1m?

Since the weight of the pointer shaft would be greater than the turning bimetal coil (i.e. the pointer would no longer be able to move).
