bourdonputket

Bourdonputket, also known as Bourdon tubes, are a type of mechanical pressure gauge. They were invented by Eugène Bourdon in 1849. A Bourdon tube is a curved, hollow metal tube that is sealed at one end and open at the other. When a fluid at a higher pressure is introduced into the tube, it causes the tube to uncoil or straighten slightly. This movement is proportional to the pressure applied.

The sealed end of the Bourdon tube is connected to a pointer or needle that moves across a calibrated scale. As the tube straightens due to pressure, the pointer moves, indicating the pressure reading. The shape of the tube can vary; common shapes include C-shaped, helical, or spiral. The material of the tube is typically brass, bronze, stainless steel, or other alloys, chosen for their strength and resistance to the fluid being measured.

Bourdon gauges are widely used due to their simplicity, reliability, and relatively low cost. They are found in a vast array of applications, including industrial processes, plumbing systems, automotive diagnostics, and scientific equipment. Despite the advent of digital pressure sensors, Bourdon gauges remain a common and effective method for pressure measurement. Their operation relies on basic mechanical principles and they do not require electrical power to function.
