P11 Diaphragm pressure gauge

Structure principle
Diaphragm pressure gauge is a closed system consisting of diaphragm body and pressure gauge, flled with sealing liquid. When pressure
acts on the diaphragm, the diaphragm is deformed. The sealing liquid transmits the force to the elastic component in the pressure gauge
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 flled between the inside of the diaphragm body and the Bourdon tube. The elastic element is also the Bourdon tube.
The diaphragm separates the corrosive fluid from the pressure gauge, thereby preventing it from corrosion.
