UV/IR Detectors for Flame Detection - Sensors Development

· The ultimate benefit of having UV and IR sensors combined in a single device is that they share the same alarm source – a real hydrocarbon fire. As mentioned, each individual sensor operates separately, but adding advanced signal processing algorithms enables the combination of the two sensors to deliver outstanding flame detector performance to a wide range of flammable liquids, …

Flame Detection and Minimizing False Alarms

· The fuel for the fire is another consideration. A hydrogen-fueled flame requires a specially tuned detector while hydrocarbon-fueled fires: …such as methane and gasoline, multi-spectrum IR detectors are typically the best choice. Jonathan explains that the flame detection equipment does typically not cause false alarms but rather: …non-flame radiation sources that fall within the field of ...

Ultraviolet / Infrared Flame Detector

Only when the defined detection criteria for both IR and UV sensors indicate a fire condition will the detector alarm. Spectral Sensitivity Range The UV/IRS fire detector responds to UV radiation wavelengths of 185 to 260 nanometres (1850 to 2600 angstroms) and IR radiation in the micron range. Note that UV radiation reaching the earth from the sun does not extend into the sensitivity ...
