Schabus Monitoring relay 1 pc(s) 201753

The flue gas thermostat is used to monitor the exhaust gas temperature in the flue pipe of heat generating equipment. The sensor of the ATW consists of a metal tube and a metal rod arranged in it with different coefficients of expansion, which give a difference in length when the temperature changes. This acts on a precision microswitch, which closes the control circuit for the KDS above a fixed limit temperature (here 40 degrees). After lowering the temperature at the sensor by approx. 15 K, the microswitch switches back and the control circuit becomes high-resistance again. Especially for the exhaust air control KDS 110 and KDS 116. Normally open contact bridged with 10k resistor at the factory.This text is machine translated.
