OGGIONI flame detectors use a microprocessor for the analysis of sophisticated electronic signals.
The UV/IR and IR3 flame detector uses the analysis of the flame flicker frequency as an additional alarm criterion. UV/IR and
IR3 flame detectors have good false alarm rejection. UV is immune to virtually all false alarm sources except arc welding. .
