ATEX Temperature Controller

Introducing the ATEX Temperature Controller-Limiter and Power Selector. The perfect solution for controlling and limiting temperature in hazardous environments where explosive gases or dust are present. This combination device is intrinsically safe and user-friendly, making it an ideal choice for those who need precise temperature control in potentially explosive atmospheres.

Comprehensive Solution for Controlling and Limiting Temperature

Featuring a comprehensive solution for controlling and limiting temperature, including power selector function, this device comes equipped with a measurement display featuring 7-segment-LED's and a relay output alarm with 1 CO contact 5A, 250 V. Additionally, the intrinsically safe and galvanic isolation connection of the Pt100 DIN EN 60751 (IEC 60751) resistance thermometer in 3- or 2-wire circuit ensures precise and accurate temperature control.
