Temperature & Pressure effects on Pressure Gauges

There are two conditions that can negatively affect a gauge’s accuracy and performance. They are temperature and vibration. Let’s go over both of these.

TEMPERATURE

For every 100-degree shift in temperature from which the gauge is calibrated, you can experience up to a two percent error in reading.

The reason for this is that it causes a change in the elasticity of the Bourbon tube element. This change is directly related to surrounding temperature.

VIBRATION:

Vibrations caused by pumps, motors, and other rotating equipment can cause excess wear and tear on pressure gauges.

After long, both of these can cause premature failure of the internal working parts inside a pressure gauge. Additionally, vibration can cause difficulty in getting an accurate reading of the gauge, even when the gauge is working properly. Exposure to continuous vibration is one of the most common causes of pressure gauge failure.
