P631, P632_High static Indicating type differential pressure switch
Service intended
P631 to P632 series are designed to measure differential pressure from 30 kPa ro 1.5 MPa at Max. working pressure up to 25 MPa.P631 to P632 series are designed to control and alarm for differential pressure, providing right time to replace air and sluge filter during the process.
