Common Failure: Mechanical Vibration 

How do I know that my gauge is experiencing vibration?

The indicators for system vibration can be seen from the exterior but there may also be internal damage to your gauge.


External Indicators

Internal Indicators

Missing pointer

Crack in bourdon tube

Black dust on dial

Worn segment gear

Scrapes on dial from loose pointer

Worn pinion gear

Missing window, window ring or back plate

Worn link

What causes vibration in my gauge?

Failure due to mechanical vibration can be caused by several things. When looking at your system, consider the following:

  • Is there vibrating equipment near the gauge?
  • Are pumps misaligned or are there reciprocating compressors?
  • How is the fixture mounted? A poor fixture mount can cause an excessive amount of vibration

Possible Risks

  • Vibration breaks movement and the movement no longer anchors the Bourdon tube
  • Failure of the Bourdon tube and gauge
  • System media releases into the environment resulting in potential injury and lost system media


Use a liquid-filled gauge in your system. A liquid filled gauge will reduce internal wear, lubricate and cool moving parts as well as dampen the effects of vibration. Available case fills include Glycerine, Silicone, Halocarbon and Fluorolube. Eliminate or reduce avoidable vibration in the system. In extreme situations you can use a snubber or a diaphragm seal with an internal restrictor (in place of a Bourdon tube style gauge) for a more robust solution.
