Stainless steel pressure gauges are widely used in petroleum, chemical, chemical fiber, metallurgy, power station, food and other industrial sectors to measure the pressure of various fluid media in the process that requires high corrosion resistance and high temperature resistance.
The stainless steel pressure gauge is composed of a pressure guiding system (including joints, spring tubes, flow-limiting screws, etc.), a gear transmission mechanism, an indicating device (pointer and dial), and a casing (including case, cover, watch glass, etc.).
The pressure gauge uses the elastic deformation of the stainless steel sensitive elements (Bourdon tube, bellows, bellows) in the watch, and then the elastic deformation is transmitted to the pointer by the conversion mechanism of the movement in the watch, causing the pointer to rotate to display the pressure.

For the instrument filled with liquid (usually silicone oil or glycerin) in the shell, it can resist the vibration of the working environment and reduce the pulsation of the medium pressure.
Installation notes:
The choice of pressure measuring point, the selected pressure measuring point can reflect the real situation of the measured pressure.
(1) Choose the part of the pipe where the measured medium flows in a straight line. Don't choose the pipe bends, bifurcations, dead ends or other places where vortexes are easily formed.
(2) When measuring the pressure of the flowing medium, the pressure point should be perpendicular to the flow direction to remove the burrs from the drilling.
(3) When measuring the liquid pressure, the pressure point should be at the lower part of the pipeline so that no gas accumulates in the pressure guiding tube. When measuring gas, the pressure taking point should be above the pipeline so that no liquid accumulates in the pressure guiding tube.
