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

What is meant by switching function?

Under switching function, we mean the opening or closing of an electrical circuit. Normally-closed contacts interrupt a circuit on rising temperature (clockwise); normally-open contacts close a circuit on rising temperature (clockwise).

Why is liquid damping an advantage with high vibration?

Since the pointer is damped and the temperature can be read better.
