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.

Are there any GOST certificates for thermowells and protection tubes?

No. GOST certificates only exist for measuring instruments and a thermowell and protection tube is only considered a component part of a thermometer.
