Which type of gauge is capable of measuring both negative and positive pressure?

• A. Absolute pressure gauge
• B. Digital pressure gauge
• C. Compound pressure gauge
• D. Simple pressure gauge

Answer: (C)

A compound pressure gauge is designed specifically to measure both negative and positive pressure, making it particularly versatile in various applications. This type of gauge operates by having a dual scale that indicates pressure below and above atmospheric levels, which is essential when monitoring systems that may experience both vacuum (negative pressure) and positive pressure conditions. In comparison to other gauges, an absolute pressure gauge measures only positive pressure relative to a perfect vacuum, while a simple pressure gauge typically focuses solely on positive pressures without incorporating the ability to measure below atmospheric levels. Digital pressure gauges may offer a wide range of features, but their capability to measure negative pressure depends on their specific design and application; they are not universally defined to do so. Therefore, the compound pressure gauge stands out because of its inherent design to encompass both pressure types effectively.
