20/20ML UV/IR

SharpEye Mini UV + IR Flame Detector


The SharpEye Mini UV/IR Flame Detector (20/20ML) is a compact flame detector featuring high sensitivity combined with enhanced nuisance alarm immunity.

This product is designed to detect hydroxy and hydrogen fires, metal and inorganic fires, as well as hydrocarbon fires at distances up to 15 m.

The UV/IR flame detector senses energy in both the ultraviolet and infrared portions of the electromagnetic spectrum. The UV sensor incorporates a special logic circuit that helps prevent nuisance activation caused by solar radiation. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.
