Bourdon Gauge

1. A Bourdon gauge is used to measure to gas pressure in a container.
2. There are 3 important components in a Bourdon gauge
3. the copper tube
4. the lever system
5. the pointer

Working Mechanism of a Bourdon Gauge

1. When the gauge is connected to a gas supply, the gas pressure will straighten the copper tube.
2. The copper tube exerts a force on the lever system and hence move the pointer. The movement of the copper tube is magnified by the lever system
3. The pointer rotates and give a reading (in unit of Pascal).
