Temperature Sensor
A temperature sensor is installed on the head of the
vane type of compressor. This sensor detects the
temperature of the refrigerant and when the refrigerant
becomes unusually hot, it cuts off the magnetic clutch,
stopping the compressor. The temperature sensor is
composed of a bimetallic strip and contacts. A bimetallic
strip is a sandwich of two metals with different rates of
expansion and it bends when heated due to these
different rates of expansion. This characteristic is
exploited when there is an excessive temperature via the
rod, which breaks the contact and switches the magnetic
clutch off.
