  •   Principle of Shock-proof pressure gauge

      It consists of a pressure guiding system (including joints, spring tubes, flow-limiting screws, etc.), gear transmission mechanism, indicating devices (pointers and dials), and a case (including case, cover, glass, etc.).

      The shell of the Shock-proof pressure gauge is an airtight structure, which can effectively protect the internal parts from environmental influences and pollution intrusion.

      The shock-proof pressure gauge is filled with damping fluid (usually silicone oil or glycerin) in the case to resist environmental vibration and reduce the influence of fluctuating pressure on the medium.

      the silicone-filled pressure gauge is also our product, welcome to consult and purchase.
