Diaphragm pressure gauge
The diaphragm pressure gauge is a closed system composed of a diaphragm and a pressure gauge, filled with sealing fluid. When pressure acts on the diaphragm, the diaphragm deforms. The sealing fluid transmits the force to the elastic component in the pressure instrument head, and the pressure value is displayed by the pressure gauge head. The force transmission of the diaphragm pressure gauge is completed by the liquid filled between the inside of the diaphragm and the Bourdon tube. The elastic component is still the Bourdon tube, and the diaphragm isolates the corrosive fluid from the pressure gauge, thereby protecting it from corrosion.
