Process pressure changes act on the diaphragm/piston assembly to actuate and de-actuate a snap-action electrical switching element at discrete process pressures. The pressure sensing element of the explosion proof Mini-Hermet pressure/compound pressure switch is a force-balanced, piston-actuated assembly sealed by the conventional Static “O” Ring type that SOR pioneered. The switching element assembly is hermetically sealed in a stainless steel capsule with the maximum explosion proof rating.

The small, compact size of the SOR Mini-Hermet makes it extremely popular in offshore oil and gas fields because it doesn’t require much space on the skids and it is corrosion resistant.
