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.

FAQ

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 Coefficie ...

What are 2-, 3- and 4-wire circuits?

They describe the number of wires with which the measuring resistor (e.g. a Pt100) is connected. While with the simplest 2-wire connection, the lead resistance can falsify the measuring result, this negative influence can be compensated within the ...
