Service intended
P690 differential pressure gauge series are designed to measure differential pressure from 25 kPa to 2.0 MPa at static pressure up to 10 MPa and have inductive contact. P690 series are designed to control alarm for differential pressure, providing the right time to replace air and sludge filter during the process.
