The low cost 20/20ML UV/IR Flame Detector has a compact, lightweight but rugged design for general purpose (non-Ex approved) areas. It detects hydrocarbon fire at distances up to 50 ft (15 m).
The 20/20ML provides a combination of UV and IR sensors and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.
