Since their introduction in the mid 1800s, pressure gauges have become the most common method of measuring pressure. The vast majority of these pressure gauges incorporate the Bourbon tube, socket and geared movement.
The reason pressure gauges are still so widely used is the fact they work under almost any condition.
However, 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.
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.
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.
Luckily, replacements are easy to locate.
