Liduid filled diaphragm pressure meter by the measurement system (including flange joints, corrugated diaphragm), drive indicating mechanism (including connecting rod, gear transmission mechanism, pointer and dial) and the housing (including the case and cover ring, etc.). The diaphragm pressure gauge shell is a splash proof structure, which has good tightness, and can protect the internal mechanism from being polluted.

Diaphragm pressure gauge principle is based on the elastic element (diaphragm deformation measurement system). Diaphragm pressure gauge pressure of the measured medium, forcing the diaphragm generate elastic distortion, displacement, through the transmission link group by transmission and amplification by the measured values indicated in the table by a pointer is fixed on the gears.

Features 

1.measuring strong corrosion, high temperature, high viscosity
2. easy to crystallize
3. easy to solidify, there are solid floating media pressure and the need to avoid the measurement of media directly into the general pressure gauge and prevent the accumulation of sediment and easy to clean the occasion.

Applications 

Liquid filled Diaphragm pressure gauges are suitable for measuring the pressure of liquids, gas, or vapors that are free of explosion hazard, non crystalline, non solidifying, high viscosity, but not corrosive to copper and copper alloys.
