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. Ranges from 0.5 to 1000 psid. Set point adjustment with calibrated scale.
