What is a common instrument used for monitoring pressure in a diaphragm?

• A. Manometer
• B. Diaphragm pressure gauge
• C. Barometer
• D. Thermometer

Answer: (B)

The diaphragm pressure gauge is specifically designed for measuring the pressure within a system, utilizing a diaphragm as its sensing element. This diaphragm flexes in response to pressure changes, translating mechanical movement into a readable output, typically on a dial or digital display. This design is particularly effective for applications requiring accurate pressure measurements across different environments and conditions, making it a common instrument in various industrial settings. In contrast, a manometer is suited for measuring pressure differences, frequently using liquid columns for reference, but it lacks the direct coupling with diaphragm-based systems that a diaphragm pressure gauge offers. A barometer is primarily intended for measuring atmospheric pressure, not the pressure of a confined system, and a thermometer is used exclusively for measuring temperature, which does not pertain to pressure monitoring. Thus, the diaphragm pressure gauge stands out as the most relevant instrument for monitoring pressure in contexts specified by the question.
