Built for the sudden pressure shocks created by water hammer, quick-closing valves, and pump trips, this gauge combines a liquid-filled case with a reinforced Bourdon tube and an overpressure stop so spikes bend neither the needle nor the calibration.

Precision instrumentation engineered for shockproof liquid filled pressure gauge applications
The Shockproof Liquid Filled Pressure Gauge is aimed at hydraulic shock rather than structural shaking. In pipelines and pump systems, a quick-closing valve, a pump trip, or a check valve slam can send a pressure wave through the fluid that momentarily multiplies the line pressure several times. A standard gauge may survive once, but each event slightly fatigues the tube and bends the pointer, so the instrument drifts or fails long before its expected life.
The gauge combines three defenses. A thick-walled, stress-relieved Bourdon tube with a high elastic limit resists permanent set under spikes. An overpressure stop positioned behind the pointer limits how far the needle can travel past full scale, avoiding bent pointers. A restrictor in the socket and a liquid-filled case damp the rise time of the pulse that reaches the movement, so the gear train is not hammered.
Production and testing take place in our 100,000-level clean workshop, where samples are pulsed with fast-rising pressure transients from a hydraulic test rig and checked for zero shift. Test results, tube batch, and calibration data are stored in our Advanced MES digital tracking system against each serial number, supporting engineers who must demonstrate that gauges used on surge-prone lines are rated for them.
Different from a seismic model, which is reinforced for ground and structural acceleration, and from an anti-vibration gauge, which damps continuous machine shaking, this version addresses the transient pressure events that occur inside the fluid itself. It is the right selection for pump discharge lines, fire pump test headers, and process lines with fast-acting valves.
