Gauges can fail due to overpressure.
Your gauge could have failed due to overpressure if you notice the pointer is pegged against the stop pin or the gauge is operating near or past maximum pressure.
Break down this common failure issue:
Causes
A gauge with the incorrect pressure range for the application, which is incapable of accurately reflecting the system pressure.
Risk
-
The Bourdon tube will rupture, causing complete gauge failure
-
System media will be released into the environment, resulting in potential injury and lost system media
Solution
Select a gauge rated to 2X the normal system operating pressure to provide a larger window of measurable pressure. In extreme cases, use a diaphragm seal solution with a super restrictor (0.3 mm) for a more robust solution.
