Diaphragm pressure gauge structure principle
The pressure gauge consists of a measuring system (including flange joint, corrugated diaphragm), drive indicating mechanism (including connecting rod, gear transmission mechanism, pointer and dial) and shell (including case and hood). It is a splash-proof structure, with good insulation, it can protect its internal institutions from contamination immersion.
The principle of the diaphragm pressure gauge is based on the deformation of the elastic element (the diaphragm on the measuring system). In the measured medium under the action of pressure, forcing the diaphragm to produce the corresponding elastic deformation --- displacement, by means of connecting rod by the transmission of the transmission and to be amplified by the fixed on the gear by the pointer will be measured in the dial On the instructions.
Diaphragm pressure gauges Advantages:
1. Excellent load performance
Linearity
3. Suitable for measuring absolute pressure, differential pressure
4. Small size, affordable
5. Can be used for viscous, slurry measurement.
Diaphragm pressure gauge Disadvantages:
1. Seismic, impact resistance is not good
2. Difficulty in maintenance
3. Lower measurement pressure.
