Talentum Triple IR Flame Detector 16519

Talentum Triple IR Flame Detector 16519

The sensor responds to low-frequency (1 to 15 Hz) flickering IR radiation emitted from flames during combustion. IR flame flicker techniques enable the sensor to operate through a layer of oil, dust, water vapour, or ice. Most other IR flame sensors respond to 4.3?m light, emitted by hydrocarbon flames. By responding to 1.0 to 2.7?m light emissions from fires almost all flickering flames can be detected.

Gas fires not visible to the naked eye e.g. hydrogen may also be detected. The triple IR photoelectric detectors (IR³), responding to neighbouring IR wavelengths, enable it to discriminate between flames and spurious sources of IR radiation. The combination of filters and signal processing allows the sensor to be used with a very low risk of false alarms in difficult situations characterised by factors such as flickering sunlight.
