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

Which gas is used as the fill fluid for gas actuated thermometers?

Helium.

What are the factors influencing the response times of thermowells and protection tubes?

Put simply, one can say that the more stable a thermowell or protection tube is constructed, the slower it reacts to temperature changes. In order to optimise the response time, there are thin wall thicknesses and low air space between sensor and the bore's interio ... More
