Description
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 that interrupts the circuit above a fixed limit temperature. After lowering the temperature at the sensor by approx. 15 K, the microswitch switches back and the circuit is closed again. Smallest design, high temperature resistant by special metal and ceramic materials.
Approved for use in heat-generating plants, TUV tested according to DIN, therefore no DIBt approval is required.
