Dual Opposed Diaphragm – Explosion Proof Differential Pressure Switch

This versatile opposed piston-type differential pressure switch from SOR is essentially two static o-ring-type pressure sensors at opposite ends of a common piston shaft.

The housing is explosion proof and the switching elements are SPDT or DPDT.

The S housing is available with a wide range of adjustable pressure ranges and performs best when system pressure is relatively constant.

Basic models with standard wetted parts are suitable for air, oil, water, and non-corrosive process fluids.
