Differential pressure switches

Posed piston-type differential pressure switch is essentially two static O-ring type pressure sensors connected at opposite ends of a common piston shaft. Weathertight or explosion proof models are available. Features include a wide variety of wetted parts, rugged construction, high-cycle rate tolerance, long life, narrow dead band, high overrange and proof pressures, self-locking adjustment, and a pressure range of 0.5 to 1000 psid.
