1, overview
YP series diaphragm pressure gauges for measuring the corrode the steel and copper and other metal liquid, gas and other medium pressure and negative pressure;VPF series anticorrosive diaphragm pressure gauges can be used to measure the corrosive liquid, gas and other medium pressure and negative pressure.

2, the structure principle of
Structure: diaphragm pressure gauge by diaphragm components, machine components, four major part pointer parts and casing connection parts.
Principle: the diaphragm pressure gauge is diaphragm as the stronger sex element, when the measured medium pressure on the diaphragm, a displacement of the diaphragm, repass machine core components, pointer parts work, made to measure the pressure indicator on the dial out clearly.
