Q

Which of the following direct pressure measuring instruments is most appropriately used for measuring most pressures, typically above 10 psig and is by far the most common type?

🔍 Key Concepts

• Direct pressure measuring instruments used in marine engineering systems • Typical working range and applications of Bourdon tube, diaphragm, bellows, and spiral/helical gauges • Which gauge construction is most common for general service pressures above 10 psig

💭 Think About

• For each gauge type, think about what pressure range it is best suited for: very low, medium, or very high? • Which of these designs is rugged, simple, and commonly seen on boiler fronts, air compressors, hydraulic systems, and engine lube oil systems? • Which design is often used for low differential pressures (like draft gauges or small pressure differences) rather than general plant pressures?

✅ Before You Answer

• Identify which type is specifically known as the standard industrial pressure gauge • Eliminate any designs that are usually reserved for very low pressure or small differential pressure measurements • Confirm which type is most likely to be seen on most machinery pressure panels aboard ship
