# Bourdon Gauge?

A bourdon gauge has a thin-walled metal tube, somewhat bent into the form of a C. A lever system is attached to its free end that magnifies any motion of the free end of the tube. On the gauge’s fixed end, is a fitting that is threaded into a boiler system.  As the boiler pressure increases, it travels through the tube. Like the snakelike paper whistle, the metal tube starts to straighten as the pressure increases inside it. As the tube then straightens, the pointer moves around a dial which indicates the pressure in psi.
A Bourdon gauge measures pressure. It consists of a thin-walled, flattened metal tube that is closed at one end. The tube is bent in the shape of a C. When pressure forces a gas into open end of the tube, it causes the walls of the tube to try to widen. This causes the tube to tend to straighten out., causing the closed end of the tube to move. The amount of this movement of the closed end is proportional to the pressure. A pointer attached to the closed end indicates the pressure on a calibrated dial.
A Bourdon gauge works by a coiled tube which senses changes in the gauge pressure. If the pressure increases, the tube will uncoil and if the pressure decreases, the tube will coil back up. It is then shown on the front of the gauge by a needle which shows the pressure. You can find more information at en.wikipedia.org
Within the Bourbon guage is a thin-walled metal tube, which is almost flattened and bent into the form of a C. Attached to its free end is a lever system that magnifies any motion of the free end of the tube. A fitting that is threaded into the boiler system is on the fixed end of the guage. As pressure increases inside the boiler, it travels through the tube. The metal tube will begin to straighten as the pressure begins to increase inside of it. The pointer moves around a dial that idicates the pressure in PSI.
A Bourdon Gauge works similar to a party whistle; the tube inside it straightens out with the application of air. As the air pressure inside the tube increases, a lever that is attached to the end of it registers psi. The Bourdon Gauge is very accurate, but also sensitive to drastic changes in pressure.
