Bourdon Presssure Guage - Pressure Measuring Device

A Bourdon pressure gauge consists of a bent tube of an elliptical cross section, a calibrated scale, gear and pinion arrangement. A typical sketch of Bourdon pressure gauge is shown in figure.
One end 'A' of the tube is sealed and its motion is transmitted to the pinion through the link E and gear.

The other end 'B' of the tube is open through which the fluid pressure is transmitted to the tube. The Bourdon pressure gauge measures the pressure difference inside the tube and the atmospheric pressure.
The bent tube tends to unbend when subjected to the fluid pressure. The deformation of thee tube is transmitted from end 'A' to the pinion and the needle will show the gauge pressure of the fluid on the calibrated scale.
