Differential pressure transmitter for gas measurement

Differential pressure transmitter for gas measurementThe differential pressure sensor is encapsulated 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.

Widely applicable for differential pressure measurement of various gases and liquids in pipelines such as petroleum, chemical, power, hydrology, etc.
