Infrared Technology for Hydrocarbon Gas Detection

variety of combustible gases the sensor can detect. Fig. 1 Catalytic Bead Sensor . Although catalytic bead sensors have been in use for decades, the technology has some drawbacks. One critical limitation is the inability to operate in an environment deficient in oxygen since the bead requires efficient oxidation of hydrocarbon gas; oxygen levels impact oxidation efficiency; and hence, the ...

How Carbon Monoxide Detectors Work | HowStuffWorks

­CO detectors can use several types of sensors to sense carbon monoxide in the air. Biomimetic sensor technology reproduces CO's effects on hemoglobin in the blood. In a biomimetic sensor, a gel changes color as it absorbs CO. A separate sensor detects the c­olor change and alerts the detector's processor to sound the alarm. Once a biomimetic ...
