What is the main function of a bourdon-tube gauge?

• A. To measure the flow rate of liquids
• B. To measure the pressure of gases or liquids
• C. To measure the temperature of a substance
• D. To measure the volume of gas within a container

Answer: (B)

The bourdon-tube gauge is primarily designed to measure the pressure of gases or liquids. It operates based on the mechanical deformation of a curved tube, which tends to straighten out as pressure increases. This change in shape is then translated into a movement that indicates pressure on a dial. The sensitivity and reliability of this device make it suitable for a wide range of applications where pressure monitoring is crucial, such as in hydraulic systems, pneumatic systems, and various industrial processes. Measuring flow rate, temperature, or volume pertains to different principles and devices that are specifically engineered for those parameters, such as flow meters for flow rate, thermometers for temperature, and gas volume meters for volume measurement. These instruments do not utilize the same mechanical principles as the bourdon tube, which is inherently focused on the correlation between pressure and the physical response of the tube.
