Bourdon Tube is a flattened length of thin hollow metal tubing which is formed into a C shape.
If the tube is closed at one end and pressurised at the other end, the flattened tube will become more circular which will cause the tube to straighten by an amount which is proportional to the applied pressure.
If a rotating needle is attached to the closed end via some gears and linking mechanisms, it is possible to transform the displacement of the Bourdon tube into a needle rotation.
If a dial is added behind the needle with calibrated pressure reading markings, it can be used as a pressure gauge.
