Differential pressure gauge with diaphragm element
Type: P660
 
Service intended
 
P660 gauge series are differential pressure gauge is designed to measure differential pressure from 4 kPa to 2.5 MPa at static pressure of 10, 25 MPa. A set of two stainless steel diaphragm mounted on a force balance allows direct reading of the actual differential pressure.
