The Bourdon pressure gauge uses the principle that a flattened tube tends to straighten or regain its circular form in cross-section when pressurized. (A party horn illustrates this principle.) This change in cross-section may be hardly noticeable, involving moderate stresses within the elastic range of easily workable materials.
The load cell is completely filled with oil. When the load is applied on the piston, the movement of the piston and the diaphragm results in an increase of oil pressure. This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose. [4] The gauge's Bourdon tube senses the

While searching for a mechanism to measure gas pressure, without the use of a mercury manometer, he imagined using the bending of a circular tube made of a metal with good elastic properties. From this he developed the Bourdon tube pressure gauge, patented in Paris on 18 June 1849, and he granted a licence to the workshops of Felix Richard ...
Murphy oil pressure gauges with switches that activate on low pressure. A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall.
A pressure sensor, a resonant quartz crystal strain gauge with a bourdon tube force collector is the critical sensor of DART. [13] DART detects tsunami waves from the bottom of the open ocean. It has a pressure resolution of approximately 1mm of water when measuring pressure at a depth of several kilometers. [14]
