How are pressure gauges protected from pressure spikes?

Pressure gauges are protected from pressure spikes primarily by using snubbers. A snubber is a device that dampens sudden fluctuations in pressure, allowing the gauge to provide accurate readings without being damaged by rapid pressure changes. When a pressure spike occurs, such as during system start-up or shutdown, the snubber introduces a delay in pressure transmission, effectively smoothing out the spikes before they reach the gauge itself.

This protection is crucial in systems where pressure can change quickly, as it helps maintain the longevity and reliability of the gauge while ensuring accurate monitoring. In contrast, using a filter, seals, or gauges with higher ratings may provide certain benefits in specific scenarios but do not specifically address the need to mitigate sudden pressure changes causing spikes. Thus, snubbers are an essential component in safeguarding gauges in environments subject to sudden pressure fluctuations.
