A Bourdon tube is often found in a

• A. Thermometer
• B. Flow meter
• C. Pressure gauge
• D. Barometer

Answer: (C)

A Bourdon tube converts pressure into mechanical movement. Its curved metal shape tends to straighten as internal pressure increases, and that motion is linked to a pointer to show a pressure reading. Because of this direct link between pressure and a readable display, Bourdon tubes are a common sensing element in pressure gauges, making them the device used to monitor system pressure in HVAC. Thermometers measure temperature, not pressure; flow meters gauge how much fluid is moving using various mechanisms; barometers measure atmospheric pressure with mercury columns or aneroid capsules. So the Bourdon tube is bestassociated with a pressure gauge.
