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.

The distance between the rails. The standard gauge in the United States is four feet, eight and one half inches established by Congress on March 3, 1863.

When a voltage source comes in between two nodes, we call it a supernode. When a current source comes in between two meshes, we call it a supermesh.
Bourdon gauge
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.

A bourdon gauge is a type of aneroid gauge. It is used to measure pressure.

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

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 used to measure pressure and as well as calibrated to measure temperature
