Description

The Thermac Detector is a heat sensitive electrical switch.
It is a fixed temperature device with a factory pre-set temperature in the range 60 ºC to 240 ºC.
The detector comprises a pair 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 a drop in temperature the procedure reverses and the contacts re-open below the set point temperature.
The detector body is a seamless one-piece unit, precision machined from AISI 316 stainless steel with high corrosion resistance. Electrical contacts are gold/silver plated and lead cables are nickel plated copper with PTFE/glass insulation. Cables are to aircraft engine specification.
The operating parts are factory calibrated and sealed against severe environmental conditions, further adjustment or calibration is not required.
