Product Description

Application

Vacuum gauge is an instrument for measuring the rarefaction or pressure of gas under vacuum. It is widely used in oil pipelines, water conservancy and hydro-power, railway transportation, intelligent buildings, production automation, aerospace, militar y industry, petrochemical, oil wells, electric power, ships, machine tools, pipeline air supply, vacuum equipment and other industries.

Theory

The measuring system of the vacuum manometer is composed of a shank, a Bourdon tube, a transmission mechanism and an indication device.
The Bourdon tube is elastically deformed under pressure and causes displacement of the its end. The displacement is amplified by the transmission mechanism which pushes the indication device, and then the pointer indicates the pressure value on the dial that engraved with the unit of measurement.
