Big Hermet – Explosion Proof Temperature Detector

The design of SOR’s explosion-proof Big Hermet temperature detector 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 detectoring element. This versatile, adjustable pressure snap detector works in a wide variety of process media and industrial applications.
