The gauge measures the pressure difference between the inside and the outside of the Bourdon tube and atmospheric pressure must be ADDED TO the gauge pressure to obtain the ABSOLUTE PRESSURE of the ...

The Bourdon tube pressure gauge is a widely employed mechanical instrument designed for the measurement and display of pressure. Its functionality encompasses the capability to gauge pressure ...

Depending on the design of the pressure gauge, it measures this in various ways. The two most common types of pressure gauges are the bourdon tube and diaphragm pressure gauge. For a bourdon tube ...

As there does not seem to be in any of the more familiar text-books of Physics or Engineering any satisfactory explanation of the action of the Bourdon gauge, the following may be of use to some ...
