Differential pressure transmitter is composed of a differential pressure sensor encapsulated in a stainless steel housing with positive and negative chamber pressure interfaces. It uses differential pressure sensors with high stability and reliability, as well as specialized electrical transmitters with high performance

The road realizes the conversion between differential pressure and electrical signals, and the overall performance is stable and reliable.

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