pressure gauge works on hooks law principle ,when we applying pressure in end connection of the pressure gauge ,the same pressure operating at end of the bourdon tube.
Because it can measure gauge of wire and has screw type structure.
You measure it with an aneroid gauge.
to measure spark plug gap
A device to measure the tire's thread depth.
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.
A Bourdon Tube or a Bellows gauge
it is used to measure pressure and as well as calibrated to measure temperature

A bourdon gauge is a type of aneroid gauge. It is used to measure pressure.
Bourdon gauge
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.
Eugene Bourdon invented and patented the Bourdon tube pressure gauge.

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