Flue gas temperature monitor - Temperature control relay 201749

Flue gas temperature monitor - Temperature control relay 201749 – Schabus – 4044764001565: Flue gas temperature monitor 201749 The flue gas thermostat is used to monitor the flue gas temperature in the flue pipe of heat-generating systems. The ATW sensor consists of a metal tube and a metal rod inside it with different coefficients of expansion, which result in a length difference when the temperature changes set limit temperature interrupts the circuit, after the temperature at the sensor has dropped by approx. 15 K, the microswitch switches back and the circuit is closed again, smallest design, high-temperature resistant thanks to special metal and ceramic materials, approved for use in heat-generating systems, TÜV tested according to DIN , therefore no DIBt approval required. Technical data: switching point: 40 °C, switching accuracy: +/- 7 K, switching differential: approx. 15 K, limit value range: limit value between 0 °C and 400 °C, operating medium: air or flue gas, permissible ambient temperature: max. 180 ° C on the switch housing, medium temperature: 0...500 °C, time constant: < 45 seconds, connection cable: 2 m, protection class according to DIN EN 60529: IP 40, switching capacity: 16(4) A 400V at cos? = 1(0.6)
