The positive and negative pressure differential sensors/transmitters are assembled from OEM silicon piezoresistive differential pressure cores, and the outer shell is made of aluminum alloy structure. The two pressure interfaces have M10 threads and a plug structure, which can be directly installed on the measuring pipeline or connected through a pressure pipe. Widely used in pressure process control fields such as boiler air supply and underground ventilation in the power and coal industries.
