Temperature switches

For each application the right temperature switch

Temperature switches are used in a variety of industrial and technical processes. If a preset temperature is reached, then the temperature switch opens or closes a corresponding switch contact. Depending on the requirements, mechanical or electronic switches can be used. In addition to electronic temperature switches and bimetal temperature switches, WIKA's wide range also includes air velocity meters and frost protection thermostats.

FAQ

What does one understand by the accuracy of mechanical pressure or temperature switches?

With the accuracy, one refers to the deviation between the set point and the actual value of the switch point. The “accuracy” is only used very rarely with mechanical pressure or temperature switches, because the set point is often set by the custome ...

What do the terms hysteresis/switch differential/dead band mean with pressure or temperature switches?

The three terms refer to the difference between the switch point and the reset point. At the switch point, the switch changes the connected circuit through its activation. At the reset point, the original status is restored. It is basically essential ...
