The Talentum® Single Infra-Red (IR) Spark Detector responds to low frequency (1 to 15 Hz.) flickering IR radiation emitted from sparks and other hot objects during combustion.
IR flame flicker techniques enable the sensor to operate through a layer of oil, dust, water vapour, or ice.
Most IR spark sensors respond to 4.3?m light, emitted by hydrocarbons. By responding to 1.0 to 3.0?m light emitted by sparks, early stage fires can be rapidly detected.
The single IR photoelectric detector responds to IR wavelengths, emitted from glowing embers and sparks and is ideal for these applications.
The combination of filters and signal processing allows the sensor to be used without risk of false alarms on dark machinery and ductwork.
