Stainless steel pressure gauges are widely used in petroleum, chemical industry, chemical fiber, metallurgy, power station, food and other industrial departments to measure the pressure of various fluid media in the process flow with high requirements for corrosion resistance and high temperature resistance.
The gauge adopts direct contact connector and pressure sensing element materials, icr18ni9t, ocr18ni12mo2ti and SUS316. The structure is fully sealed. The stainless steel pressure gauge has strong ability to prevent the corrosion of the measured medium and environmental corrosion. Stainless steel pressure gauges are suitable for highly corrosive media suitable for the detection of stainless steel components and harsh external corrosive environment. Stainless steel pressure gauges are widely used in petroleum, chemical, metallurgy and other industries.
The stainless steel pressure gauge is composed of pressure guiding system (including joint, spring tube, current limiting screw, etc.), gear transmission mechanism, reading device (pointer and dial) and shell (including case, cover, glass, etc.).
The pressure gauge displays the pressure through the elastic deformation of the stainless steel sensitive elements (Bourdon tube, bellows and bellows) in the gauge, and then the elastic deformation is transmitted to the pointer by the conversion mechanism of the movement in the gauge, causing the pointer to rotate.
For instruments filled with liquid (generally silicone oil or glycerol) in the shell, it can resist severe vibration in the working environment and reduce the pulsation of medium pressure.
