PP Plastic Diaphragm Pressure Gauge for Chemicals & Gases

786 diaphragm pressure gauge

structural principle

A diaphragm pressure gauge is a closed system consisting of a diaphragm body and a pressure gauge, filled with sealing fluid. When pressure is applied to the diaphragm, it undergoes deformation. The sealing fluid transmits 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 a diaphragm pressure gauge is completed by the liquid filled between the diaphragm body and the Bourdon tube. The elastic element is still the Bourdon tube, and the diaphragm plate isolates corrosive fluids from the pressure gauge, thereby preventing corrosion.
