The Demco Detector is a heat sensitive electrical switch. It is a fixed temperature device with a factory pre-set temperature 232°C.
The D-143 Detector comprises of normally open electrical contacts mounted within a stainless steel probe. A rise in temperature will cause the contacts to close at the set point temperature. With the drop in temperature the procedure reverses and the contacts re-open below set point temperature.
The detector body is a precision machine from AISI304 Stainless Steel with high corrosion resistance. The operation parts are factor calibrated and sealed against severe environmental condition, further adjustment or calibration is not required.
