20/20ML Mini UV/IR Flame Detector
Low cost, compact and lightweight UV/IR dual-sensor with high-speed response and large field of view
The low cost, compact, lightweight 20/20ML UV/IR Flame Detector comprises both UV and IR sensors, detecting hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires at distances up to 50 ft (15 m). 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.
