A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside, there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is less than the ambient air pressure), or the force will tend to straighten out the pipe (if the pressure is higher inside). This force can be measured, and from the measurement of this force, the gauge pressure within the pipe can be calculated.
A Bourdon Tube or a Bellows gauge
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.
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.
It causes the Bourdon tube to straighten.
Pressure guage is first to come to mind.
Eugene Bourdon invented and patented the Bourdon tube pressure gauge.
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.
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.

In 1849, the Bourdon tube pressure gauge was patented in France by Eugene Bourdon.

A Bourdon Gauge is a pressure indicator, it works with a "C" shaped tube oval in cross section that tries to straighten under pressure. When the tube tries to straighten it pulls on a connecting arm which turns a needle that is against a card that states the pressure. A bourdon gauge lets you know when a stoem is headed your way.It is like a warning tool because it lets you know early so you can prepare for the storm.
Bourdon gauge
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.
It causes the Bourdon tube to straighten.
