The pressure inside a Bourdon tube pressure gauge causes the tube to straighten. As the internal pressure increases, it exerts force on the curved shape of the tube, causing it to uncoil or straighten out. This movement is then translated into a pointer movement on the gauge dial, indicating the pressure level.
The bourdon tube is a curved oval cross-sectional tube. The tendency of a fluid under pressure to try to shape its container, the tube, into a spherical shape causes the tube to elongate, moving the dial mechanism to a position indicating the application of pressure. The greater the pressure applied the greater the movement of the tube.
Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.

A bourdon tube is commonly found in pressure measuring devices such as pressure gauges and manometers. It is used in various applications, including industrial machinery, HVAC systems, and automotive engines, to measure and display pressure levels. The tube's mechanical deformation in response to pressure changes is converted into a readable dial or digital output. Additionally, bourdon tubes can also be found in some types of flow meters.
Eugene Bourdon invented and patented the Bourdon tube pressure gauge.
In 1849, the Bourdon tube pressure gauge was patented in France by Eugene Bourdon.
It causes the Bourdon tube to straighten.
An elastic transducer, that is bourdon tube which is fixed and open at one end to receive the pressure which is to be measured. The other end of the bourdon tube is free and closed. The cross-section of the bourdon tube is eliptical. The bourdon tube is in a bent form to look like a circular arc. To the free end of the bourdon tube is attached an adjustable link, which is inturn connected to a sector and pinion as shown in diagram. To the shaft of the pinion is connected a pointer which sweeps over a pressure calibrated scale.
The pressure inside a Bourdon tube pressure gauge causes the tube to straighten. As the internal pressure increases, it exerts force on the curved shape of the tube, causing it to uncoil or straighten out. This movement is then translated into a pointer movement on the gauge dial, indicating the pressure level.
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.

Pressure guage is first to come to mind.
Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.
A bourdon tube is a type of curved tube where the inside radius is smaller than the outside radius. As Force = Pressure x Area this means that when a pressure is applied internally to the tube the greater surface area on the outside causes the tube to straighten out. This is connected via a mechanical linkage to dial on the front of the gauge. Your typical industrial pressure gauge is the Bourdon Tube tyep.

It is the gearing, becasue the gears amplify the movement of the bourdon tube into a much larger movement of the needle on the dial. the gears are a mechanical amplifier.
