Temperature controllers

Temperature controllers with the latest technology

The compact temperature controllers from WIKA offer display, control and monitoring of temperatures. The configuration of the sensor input is made via the multi-function input. Resistance thermometers, thermocouples and standard industrial signals, such as 4 ... 20 mA, serve as the input variable of a temperature controller. The monitoring output can be set either as relay (for slow control), as logic level for the control of electronic solid-state relays (for fast control and high current loads) or as a continuous 4 ... 20 mA output.

What is thermal voltage (or the Seebeck effect)?

The effect, named after Thomas Johann Seebeck, describes the fact that an electric voltage exists when two different metallic conductors are connected at two different points, if there is a temperature difference between the connected and the open en ...

How does a resistance thermometer work?

The electrical resistance of a resistance thermometer's sensor changes with the temperature. As the resistance of measuring resistors to EN 60751 (2009-05) increases with rising temperature, we refer to it as PTC (Positive Temperature Coefficient ...
