Diaphragm pressure gauge by indirect measurement of diaphragm, in measured media deformation under pressure, sealed by pressure to form a pressure equivalent to the P, transfer to the pressure gauge, display the measured media pressure value. Diaphragm pressure gauge is mainly used in the following conditions:
First, the measurement of corrosion resistance requirements of the occasion pressure (measured media corrosive, different corrosive media to use different materials);
Two, food hygiene requirements, due to the ordinary pressure gauge measurement of pressure when the medium is not flowing inside the pressure gauge, easy to repeat pollution.
Diaphragm pressure gauge is suitable for measuring the pressure of liquid, gas or granular solid medium with large viscosity, Yi Jiejing, high corrosion resistance and high temperature. Isolation diaphragm has a variety of materials, in order to adapt to a variety of different corrosive media.
Ordinary pressure gauge is suitable for measuring the risk of non explosion, non crystalline, non solidification and the pressure of the liquid, vapor and gas, etc..
