A Bourdon Tube is a mechanical device used to measure pressure. It consists of a curved, hollow tube that straightens when pressure is applied inside it. This movement is then translated into a dial reading, allowing users to see the pressure level in various systems, such as gas or liquid pipelines. Bourdon tubes are commonly found in pressure gauges and are valued for their accuracy and reliability. They can measure a wide range of pressures, making them useful in industries like manufacturing, automotive, and aerospace. Their simple design and functionality have made them a standard tool for pressure measurement.
