🔍 Key Concepts

• Combustible gas indicator (CGI) basic operating principle • How flammable gas concentration is sensed and turned into a readable value • Difference between detecting presence vs. physically collecting or changing the vapor

💭 Think About

• Think about what has to physically happen to the vapor inside the instrument so that it can be turned into an electrical signal or dial reading. • Which option best describes the internal detection method used in many portable gas indicators for measuring % of lower explosive limit (LEL)? • Ask yourself: does a CGI mainly collect/hold the vapor, or does it briefly act on the vapor so that a sensor response can be measured?

✅ Before You Answer

• Which choice matches the idea of a sensor element that responds when exposed to a flammable mixture? • Eliminate options that sound like bulk handling of gas (e.g., total amount by weight or volume) rather than sensing concentration. • Consider which method would realistically create a change that an internal sensor/electrical circuit can easily detect and quantify.
