Differential pressure of pressure transmitter

Differential pressure of pressure transmitterIt is composed of packaging the differential pressure sensor in a stainless steel housing with positive and negative chamber pressure interfaces. It uses high stability and reliability differential pressure sensors and high-performance transmitter dedicated circuits to achieve the conversion of differential pressure and electrical signals, with overall stable and reliable performance.

Differential pressure sensor transmitters are widely used for differential pressure measurement of various gases and liquids in pipelines such as petroleum, chemical, power, hydrology, etc.
