It is composed of a pressure guiding system (including joints, spring tubes, current-limiting screws, etc.), a gear transmission mechanism, a counting device (pointer and dial), and a housing (including a watch case, watch cover, watch glass, etc.).
The shell of the shockproof pressure gauge is air-tight structure, which can effectively protect the internal parts from environmental impact and pollution intrusion.
The shock-resistant pressure gauge is filled with damping liquid (usually silicone oil or glycerin) in the shell, which can resist the vibration of the working environment and reduce the pulsating influence of the medium pressure.
