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 an electronic contact (model 830.E)?

Electronic contacts are fitted with non-contact slot sensors. They are especially suitable for oil-filled gauges and should be preferred for low voltages and small DC loads, such as for the signal input for a PLC (programmable logic controller).

What is a reed contact (model 851)?

Reed contacts are often used for switching small voltages and currents, since their hermetically-sealed design, in combination with contacts in inert gas, cannot become corroded on the contact surfaces. Their high reliability and low contact resistance make them su ... More
