How do Bourdon Tube Pressure Gauges Work

A bourdon tube pressure gauge is a mechanical pressure measuring instrument that reads the pressure without requiring any electrical power. It is generally used for the measurement of pressure from 0.6 to 7000 bar (8 to 10000 psi). It is the most common type of pressure gauge and is used by industries for its high accuracy and precision, especially for high-pressure applications. Bourdon tube pressure gauges are suitable for liquid or gaseous media for vacuum, low and high-pressure applications. Compared to other types of pressure gauge, the bourdon tube pressure gauge advantages are:

• Relatively low cost

• Compact design

• Safety in the measurement of high-pressure ranges

• Measurement accuracy

• Use with heavy vibration application and dynamic pressure load
