🔍 Key Concepts

• Very small pressure differences compared with atmospheric pressure (e.g., furnace draft) • Sensitivity and resolution of different mechanical pressure gauges • Typical applications of Bourdon, diaphragm, and bellows gauges

💭 Think About

• Which type of gauge is designed to respond accurately to very low pressure or slight vacuum rather than high system pressures? • Think about boiler furnace draft: is this a high positive pressure, a strong vacuum, or a very small pressure difference from atmosphere? • Which of these instruments is commonly used for draft gauges or manometers in boiler air/gas paths?

✅ Before You Answer

• Identify which gauge type is best suited for low differential pressure (just above or below atmospheric). • Eliminate any gauge types that are mainly used for moderate to high pressures (hundreds or thousands of kPa/psi). • Match the gauge type you choose with what is normally used for boiler draft measurement in marine practice.
