Why did my pressure gauge fail?

Pressure gauges most often fail because they aren’t suited to the conditions they’re exposed to. Common causes include mechanical vibration or pulsation, which wear internal parts and make readings unreliable; temperature extremes and pressure spikes/overpressure that physically damage the gauge; and corrosion, clogging, or mishandling, which degrade components or block the sensing mechanism.

Each of these factors can distort or disable the Bourdon tube and pointer mechanism over time, leading to failure. Choosing a gauge with the right design and protection for your specific application reduces the likelihood of these failures.
