Product introduction

Diaphragm pressure gauges are suitable for measuring the pressure or negative pressure of various fluid media with certain corrosiveness, non-solidification or non-crystallization. Its corrosion resistance depends on the diaphragm material. The pressure guide system and shell of the stainless-steel diaphragm pressure gauge are made of stainless steel, which has strong corrosion resistance. It is mainly used to measure the micro pressure of gas and liquid in chemical, petroleum and textile industries, especially for the micro pressure measurement of highly corrosive and viscous media (non-solidified and non-crystallized).

Instrument principle

The instrument is composed of measuring system (including flange, joint and corrugated diaphragm), transmission indicating mechanism (including connecting rod, gear transmission mechanism, pointer and dial) and shell (including meter case and cover ring). The instrument enclosure is of splash-proof construction and has good tightness, so it can protect its internal mechanism from dirt immersion.

The working principle of the instrument is based on the deformation of the elastic element (diaphragm on the measuring system). Under the action of the pressure of the measured medium, the diaphragm is forced to produce a corresponding elastic deformation displacement, which is transmitted and amplified by the connecting rod group through the transmission mechanism, and the measured value is indicated on the dial by the pointer fixed on the gear.
