Question 1 of 27070

Which of the following direct reading pressure gauges is capable of measuring two pressures and displaying the difference between the two?

🔍 Key Concepts

• Differential pressure vs. dual pressure measurement • How a gauge can both sense two separate pressures and show their difference • Typical uses of compound, simplex, and duplex gauges in marine systems

💭 Think About

• Which type of gauge is specifically designed so that its main reading is the difference between two pressures, not just each pressure separately? • Think about how a compound gauge is typically used on pumps and refrigeration systems—what two things does it read, and does it actually show a difference? • When you hear simplex and duplex, what do those prefixes suggest about the number of sensing elements and what is displayed?

✅ Before You Answer

• Identify which option is explicitly associated with measuring across an orifice, filter, or membrane to show pressure drop. • Distinguish between a gauge that shows one pressure that can be above or below atmosphere versus one that works with two separate pressure sources. • Confirm which gauge type is standard when monitoring pressure drop across a filter or heat exchanger on a vessel.
