Diaphragm pressure gauge
One. Product overview
YPF series diaphragm pressure gauge is suitable for measuring has certain corrosion resistance, the solidification or amorphous pressure or negative pressure of various kinds of fluid medium.Diaphragm pressure gauge corrosion resistance depends on the diaphragm material.
2. Structure theory
Diaphragm pressure gauge by measuring system (including flange joint, corrugated diaphragm), transmission indicating device (including connecting rod, gear transmission mechanism, pointer and dial) and the shell (including case and cover ring), etc.Diaphragm pressure gauge shell for splash structure, good tightness, it can protect the internal institution from filthy immersed.
Principle of diaphragm pressure gauge is based on the elastic deformation of components (diaphragm) on the measurement system.Diaphragm pressure gauge in the measured medium pressure, force - displacement corresponding elastic deformation of diaphragm, with the help of a connecting rod set of the transmission mechanism of the transmission and amplification by pointer fixed on the gear by measured values will be indicated on the dial out.
