[0002] Seismic pressure gauges are mainly used in places with severe vibration. They can withstand pulsation, impact and sudden unloading of the medium. The instrument indication is stable and clear and has good seismic resistance. This is achieved by filling the instrument with damping fluid, such as silicone oil or glycerin.
