Structural principle of seismic pressure gauge
The anti-vibration pressure gauge is composed of a pressure guiding system (including joints, spring tubes, current-limiting screws, etc.), a gear transmission mechanism, an indicating device (pointer and dial), and an outer casing (including the case, cover, glass, etc.). Shockproof pressure gauge housing is air-tight structure, filled with damping fluid (usually silicone oil or glycerin) in the housing, which can resist working environment vibration and reduce the pulsation effect of medium pressure
