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. Sensors, thermocouples and standard industrial signals, such as 4 ... 20 mA, serve as the input variable of a temperature controller. The control 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 happens when a thermocouple is located in an ambient temperature higher than 185°F (85°C)?

While thermocouples have operating temperatures of up to 2,192°F (1,200°C), their ambient and storage temperature range is −40°F to 176°F (−40°C to 80°C). Above 185°F (85°C), there will be significant errors in temperature readings and damage to th ...

What do Pt100 and Pt1000 refer to in an RTD?

Pt is the atomic symbol for platinum, the most common metal used in resistance thermometers (RTDs). Pt100 sensors have a nominal resistance of 100Ω at ice point (0°C), while Pt1000 sensors’ nominal resistance at 0°C is 1,000Ω. See this blog for mor ...
