Abstract
PURPOSE: To readily control the temperature of a facility by mounting a housing containing a temperature-sensitive switching circuit, an alarm circuit, and a power supply directly at an object to be measured.
CONSTITUTION: A permanent magnet plate 2 is provided as mounting means to an object to be controlled at one end face of a cylindrical housing 1, and a heat-sensitive thyristor 5 as a heat-sensitive element of a temperature sensitive switching circuit for detecting and operating the temperature of the object is so provided through an elastic member at the center of the plate 2 as to partially project from the surface of the plate 2. A light emitting diode 6 for emitting an alarm is provided at the other and face of the housing 1, end a temperature sensitive switching circuit, an alarm circuit and a power supply are contained in the housing 1.
