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 effect does poor insulation resistance have?

In accordance with DIN EN 60751 section 6.3.1 the insulation resistance between each measuring circuit and the sheath, at a minimum test voltage of 100 V DC, must not be less than 100 MOhm. Should the insulation resistance be too low, a measuring err ...

What does "positive temperature coefficient thermistor" mean?

Positive temperature coefficient thermistors conduct electricity worse at higher temperatures than at lower temperatures. They are also known as PTC resistances (Positive Temperature Coefficient). Typically PTC are used in high-value temperature meas ...
