Description

P680 series are differential pressure gauge is designed to measure differential pressure from 25 kPa to 2.0 MPa at static pressure 10 MPa. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure. The contacts uses a reed switch for warning and control applications.
