Atex High Temperature Thermocouples

Atex High Temperature Thermocouples

Atex thermocouple for high temperature working cycles in industrial processes with explosion risks

ATEX thermocouples ASTC-G-Ex series allow the measurement of high temperatures up to 1800 °C in gas and powder in potentially explosive atmospheres, with basic Ex d protection and possibility of integrating intrinsic safety features, for the circuit part, through the use of an ATEX Ex ia transmitter

Unlike the ATEX thermocouples ASTC-H-EX series, they allow a higher temperature measurement thanks to the use of a ceramic sheath.
