Eugène Bourdon

Eugène Bourdon was a French engineer and inventor best known for developing the Bourdon tube, a device used to measure pressure. The Bourdon tube is a hollow, curved metal tube that expands or contracts with pressure changes inside it. This movement is transferred to a mechanical indicator, allowing accurate measurement of gases or liquids' pressure levels. His invention is widely used in many industries, including HVAC, automotive, and industrial processes, due to its reliability, simplicity, and durability in providing pressure readings without the need for electronic components.
