Service intended
The P650 series are designed to measure a differential pressure from 25 kPa to 2.0 MPa at static pressure up to 10 MPa, and have electrical contact. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure. These models are designed to control and alarm for a differential pressure.
