It is composed of pressure guiding system (including joint, spring tube, current-limiting screw, etc.), gear transmission mechanism, indicator device (pointer and dial) and case (including case, cover, glass, etc.).
The shock-proof pressure gauge housing is of air-tight structure, which can effectively protect the internal parts from environmental impact and pollution invasion.
Shockproof pressure gauges are filled with damping fluid (usually silicone oil or glycerin) in the case to resist ambient vibration and reduce the impact of fluctuating pressure on the medium.
