Pressure Spikes Leading to Gauge Failure

Gauges can fail due to spikes in pressure.

If you notice a bent, broken, or knicked prointer, your gauge could be experiencing failure due to a pressure spike. 

Break down this common failure issue:

Causes

•  A pressure spike can be caused by several things. When looking at your system, consider the following:

• Is there a pump going on or off?

• Is there a valve being opened or closed, causing a spike or sudden drop in the system pressure?

   

Risk

• An abrupt increase/decrease in pressure leading to a Bourdon tube rupture and gauge failure

• System media releases into the environment, causing potential injury and loss of system media

Solution

• Evaluate system design to eliminate unpredictable spikes. Resize the gauge to select one with a larger pressure range to accommodate expected spikes in pressure.
