Mini-Hermet – Explosion Proof Pressure/Compound Pressure Switch
30 in Hg VAC to 7000 psi, 1 bar VAC to 480 bar
Unit: ATEX, UL/CSA, GOST, INMETRO, RTN, SIL; Snap Switch: ATEX, TestSafe (SAA), UL/CSA
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.
