Diaphragm pressure gauge is suitable for measuring has certain corrosion resistance, the solidification or amorphous pressure or negative pressure of various kinds of fluid medium.Corrosion resistance depends on the diaphragm material.
Diaphragm pressure gauge structure principle
Instrument by measuring system (including flange joint, corrugated diaphragm), transmission indicating device (including connecting rod, gear transmission mechanism, pointer and dial) and the shell (including case and cover ring), etc.Instrument shell for splash structure, good tightness, it can protect the internal institution from filthy immersed.
Principle of instrument is based on the elastic deformation of components (diaphragm) on the measurement system.Under the effect of pressure measured medium, the force - displacement corresponding elastic deformation of diaphragm, with the help of a connecting rod set of the transmission mechanism of the transmission and amplification by pointer fixed on the gear by measured values will be indicated on the dial out.
Diaphragm pressure gauge main technical instructions
Level of accuracy: 2.5
Using the environment temperature: - 40 ~ + 70 ℃;Relative humidity is not greater than 90%
Temperature: temperature from 20 + 5 ℃, the temperature additional error is not more than 0.04% / ℃
Work location: vertical installation.
