Stainless steel pressure gauge is widely used in petroleum, chemical, chemical, chemical fiber, metallurgy, power station, food and other industrial sectors for corrosion resistance, high temperature resistance requirements of the process of measuring the pressure of a variety of fluid medium.
Structure principle
Stainless steel pressure gauge pressure guide system (including joint, a spring tube, limiting screws), gear transmission mechanism, shows the number of device (pointer and dial) and the housing (including watchcase, table cover, a watch glass, etc.) the composition.
The elastic deformation of the pressure gauge through the table so sensitive element (Bourdon tube, bellows, bellows tube), by the table movement conversion mechanism will elastic deformation of conduction to the pointer, cause the pointer to rotate to show the pressure.
In the case of a liquid filled (generally silicone oil or glycerin) instrument, the influence of the vibration on the working environment and the reduction of the pressure of the medium can be compared.
