What type of primary element for a pressure transmitter would be most suitable for measuring oil- fired boiler furnace and forced-draft pressures?

🔍 Key Concepts

• Types of pressure elements used in transmitters (Bourdon tube, bellows, diaphragm, strain gage) • Typical pressure ranges and sensitivity needed for furnace draft and forced-draft air systems • Suitability of different sensors for very low pressure / slight vacuum measurements

💭 Think About

• Compare which sensor types are best for high pressures versus very low pressures or small differentials • Think about whether boiler furnace draft pressure is large or actually a very small positive/negative pressure relative to atmosphere • Consider which element gives the best sensitivity and accuracy at low differential pressures rather than mechanical robustness at very high pressures

✅ Before You Answer

• Identify which options are commonly used for high-pressure measurements and may not be ideal for tiny draft pressures • Identify which options are designed for low-pressure or differential-pressure measurement (especially in air systems) • Ask yourself: which sensor type will respond accurately to small changes around atmospheric pressure rather than needing large pressure to move it?
