ABSTRACT:
A temperature sensor includes a liquid-filled sensor tube, an expansion diaphragm assembly and a capillary tube maintaining communication between the sensor tube and the diaphragm assembly for introducing into the diaphragm assembly temperature-dependent amounts of liquid for causing displacement of a diaphragm component to thereby actuate a switch. The expansion diaphragm assembly comprises a stable carrier plate to which there is affixed a circular, resilient, expandable diaphragm disc having a flat circumferential edge zone.
