Flange Diaphragm Pressure Gauge

Diaphragm pressure gauge is an instrument used to measure the pressure of fluid media,especially suitable for various corrosive,non solidifying or non crystalline fluid media. Its working principle is based on the deformation of elastic elements (such as corrugated membranes) under the pressure of the measured medium, which is converted into the movement of the pointer through the transmission mechanism, thereby indicating the pressure value on the dial.

Scope and Characteristics: Diaphragm pressure gauges are suitable for measuring the pressure of liquids, gases, or vapors that are non explosive,non crystalline,non solidifing,and have no corrosive effect on copper and copper alloys.lt is particularly suitable for measuring small pressures of gases and liquids in the chemical, petroleum, and textile industries, especially for measuring small pressures of highly corosive and viscous media.

The structure and working principle of a diaphragm pressure gauge mainly consist of a measuring system (including flange joints, corrugated diaphragms), a transmission indicator mechanism (including connecting rods, gear transmission mechanisms, pointers, and dials), and a housing (including a case and cover ring). Under the pressure of the measured medium, the diaphragm undergoes coresponding elastic deformation, which is transmitted to the pointer through the linkage mechanism, causing it to indicate the pressure value on the dial.

Type and specification

There are various types of diaphragm pressure gauges, including ordinary diaphragm pressure gauges, stainless steel diaphragm pressure gauges, corrosion-resistant and shock resistant diaphragm pressure gauges, etc.Different types and specifications of diaphragm pressure gauges are suitable for different measurement requirements and environmental conditions. For example, stainless steel diaphragm pressure gauges have high corrosion resistance and are suitable for corrosive media; The shock resistant diaphragm pressure gauge has good shock resistance and is suitable for environments with large vibrations.

Application

Diaphragm pressure gauges are widely used in industrial fields such as chemistry, petroleum, and textiles to measure the pressure or negative pressure of various fluid media. Its high precision and excellent corrosion resistance make it play an important role in these fields.
