The design of the SOR explosion proof, Big Hermet temperature switch is based on the time-tested vapor – pressure thermal system. Process temperature changes cause proportional vapor pressure changes in the sensing bulb that act on the diaphragm/piston assembly to actuate/deactuate an electrical switching element. This versatile, adjustable pressure snap switch works in a wide variety of process media and industrial applications.
