A Bourdon Gauge is a mechanical device used to measure pressure. It consists of a curved tube that straightens when pressure is applied. This movement is translated into a dial reading, allowing users to see the pressure level in various systems, such as gas or liquid pipelines. These gauges are commonly found in industries like manufacturing, automotive, and HVAC (heating, ventilation, and air conditioning). They are valued for their durability and accuracy, making them essential tools for monitoring and controlling pressure in different applications.
