The flame detectors respond to light emitted from
flames during combustion.
The detectors discriminate between flames and
other light sources by responding only to low
frequency flickering produced by flames (typically
1 to 15Hz). The detectors ignore fixed light
sources and rapidly flickering illumination
predominantly produced by lighting.
The flame flicker techniques have the advantage
of still allowing the detection of flames through a
thin layer of oil, water vapour, ice or dust. This
makes these detectors particularly useful in
industrial applications.
Full details of the principles of operation,
electrical description, and other detailed technical
data are published in the products individual data
sheet.
