Question 1 of 27070

Which of the following direct reading gauge types is the most popular type used for local display of pressures in the engine room?

🔍 Key Concepts

• Direct-reading pressure gauges used on engine room panels • Basic working principles of Bourdon tube, diaphragm, bellows, and helix/spiral gauges • Common use: which gauge type you most often see as a round dial with a pointer for air, lube oil, fuel oil, and cooling water pressures

💭 Think About

• Think about which type is standard on most machinery and piping systems, not special-purpose or low-pressure applications • Consider which of these mechanisms can safely measure a wide range of pressures (from relatively low to quite high) and is rugged and cheap to make • Recall what the typical round dial pressure gauge in industry and on ships looks like internally and which principle it usually uses

✅ Before You Answer

• Identify which options are more often used for low-pressure or differential pressure rather than general machinery pressures • Verify which type is described in textbooks as the most common industrial pressure gauge • Eliminate any types that are mainly used where very small pressure changes must be detected, rather than for general engine room line pressures
