Atex Thermocouple

Atex Thermocouple

Atex certified thermocouple for temperature measurements in potentially explosive atmospheres due to the presence of gases, vapors, powders and liquids.

ATEX thermocouples of the ASTC-H-Ex series are the right solution for the measurement of high temperatures up to 1300 °C in gases and powders in potentially explosive atmospheres, with basic Ex d protection and possibility to integrate, for the circuit part, the intrinsic safety through the use of an ATEX Ex ia transmitter.

Unlike Pt100 Atex RTD, these transmitters are more resistant to vibrations, have faster response times to temperature variations and can measure temperatures above600 °C.
