Application
Precision pressure gauges are used to verify pressure gauges and to accurately measure the pressure of liquids, gases and vapors that do not corrode copper and its alloys. It can also be used for verification or verification of other pressure measuring instruments and other types of instruments with a certain functional relationship of pressure parameters.
principle
Precision pressure gauges consist of measuring systems (including joints, Bourdon tubes, etc.), transmission mechanisms (including tie rods, gearing mechanisms), indicating components (including hands and dials) and housings (including table lights, village rings and watch glass). The composition, its elastic components are specially processed and matched with special movement components, and the two are combined.
The working principle of the precision pressure gauge is that when the pressure of the measured medium acts on the elastic component, it causes elastic deformation displacement, and the transmission mechanism is amplified by the pulling rod, and the measured pressure is indicated by the indicating device.
