Bourdon tube gauges

A Bourdon tube gauge measures pressure using a curved metal tube that straightens as pressure inside it increases. When pressure rises, the tube uncoils slightly, moving a connected pointer on a dial. This mechanical movement provides a direct reading of the pressure in fluids or gases. The design is simple, reliable, and commonly used in various industries, from water systems to industrial equipment. Essentially, the Bourdon tube converts pressure changes into mechanical motion, allowing for accurate pressure measurement without electronic components.
