Including joints, spring tubes, current limiting screws, etc.), gear transmission mechanism, display device (pointer and dial) and housing (including watch case, watch cover, watch glass, etc.).

        application:

        The shock-resistant pressure gauge is suitable for places with severe environmental vibration, which can withstand the pulsation, impact and sudden unloading of the medium, and the indicator of the instrument is stable and clear. It is widely used in machinery, petroleum, chemical industry, metallurgy, mining, electric power and other departments to measure the pressure of non-corrosive media for copper and copper alloys.
