WebApr 11, 2024 · Flame detectors and sensors are opto-electronic devices used to sense the presence (or absence) and quality of fire and provide signals to the inputs of control devices. A flame detector typically relies on ultraviolet or infrared detection of the presence of flame and finds use in many combustion control applications such as burners. Flame ... WebJul 1, 2005 · A flame ionization detector (FID) is also capable of a relatively low detectable limit, albeit, slightly higher than a PID, for many compounds, 200 ppb or less. The FID further offers a wider dynamic range (0-50,000 ppm or so) and is highly sensitive to virtually all hydrocarbon vapors, including methane. It is also extremely stable and ...
