WISE CONTROL INC : P621, P622_Indicating type differential pressure switch

Service intended

P621 to P622 series are designed to measure differential pressure from 30 kPa ro 1.5 MPa at Max. working pressure up to 5 MPa.P621 to P622 series are designed to control and alarm for differential pressure, providing right time to replace air and sluge filter during the process.
