Bourdon tube theory

A Bourdon tube is a device used to measure pressure, often found in gauges. It consists of a curved metal tube that tends to straighten when pressure inside increases. As the pressure rises, the tube’s shape changes, causing a connected pointer to move proportionally. This mechanical movement translates the internal pressure into a visible reading on a dial. The design allows for precise measurement over a wide range of pressures, making Bourdon tubes reliable and widely used in various industrial and scientific applications.
