Q

Which of the following system applications would require the use of a siphon tube (pigtail) to prevent gauge damage?

🔍 Key Concepts

• Siphon tube (pigtail) purpose – what it protects the pressure gauge from • Phase of the medium – is it liquid, gas, or vapor under high temperature? • Condensate seal – which system naturally forms water that can sit in the pigtail?

💭 Think About

• Ask yourself: a siphon tube holds a loop of liquid to shield the gauge from what specific condition? • Which of these systems commonly operates at temperatures high enough to quickly damage a standard pressure gauge if connected directly? • In which system would you expect continuous formation of condensate inside the line that could be used as a protective fluid seal?

✅ Before You Answer

• Identify which choice normally involves very high temperature in addition to pressure, not just pressure alone. • Consider which system would naturally produce condensed water in the line that can sit in the pigtail to protect the gauge. • Eliminate options that are primarily cool liquids or gases at moderate temperature, where only pressure (not heat) is the main concern.
