Diaphragm pressure gauge for measuring a certain corrosive, non-freezing or crystallization of a variety of fluid media pressure or negative pressure. Diaphragm pressure gauge corrosion resistance depends on the membrane material.

¡ôStructure principle
|
Diaphragm pressure gauge from the measurement system (including the flange joint, corrugated diaphragm), the transmission indication institutions (including connecting rod, gear transmission, pointer and dial) and housing (including Case and Hood) and so on. Splash diaphragm pressure gauge shell structure, with good tightness, it can protect its internal organs from contamination ingress.
The role of the diaphragm pressure gauge theory is based on the elastic element (measuring system on the diaphragm) deformation. Diaphragm pressure gauge in the tested medium pressure, forcing the diaphragm to produce the corresponding elastic deformation --- displacement, with the linkage groups and transmission by the transmission to zoom from a fixed to a pointer on the gear will be measured by Value indicated on the dial out.
