Opposed Piston – Weatherproof Differential Pressure Switch

The SOR weatherproof opposed piston type differential pressure switch is basically two static o-ring type pressure sensors at opposite ends of a common piston shaft. The housing is weatherproof or can be upgraded to an explosion-proof rating. Basic models with standard wetted parts are normally suitable for air, oil, water, and non-corrosive process fluids. Operating performance is optimized when system pressure is relatively constant.
