The SharpEye Single-IR Optical Flame Detector (20/20R) incorporates advanced flame analysis tools, combined with a cost effective design to produce a low-cost flame detector. The 20/20R Flame Detector was designed to provide early warning of flaming fires involving organic (hydrocarbon fuels and vapors) materials. The detector contains an infrared sensor and optical
filter that provides maximum sensitivity to the CO2 emission spectral band at 4.4 microns and improved immunity to false alarms caused by environmental IR emitting sources, including sunlight and IR projectors. The detector was designed to withstand "harsh" environmental conditions, including extreme temperatures, high humidity, vibrations, etc.
A cost-effective, explosion-proof, single IR detector that works in the 4.4 micron range!
