The Spectrex 20/20ML Series UV/IR Flame Detectors. These detectors offer a lower cost, lower power, compact design in a general purpose (non-Ex approved) flame detection. The 20/20ML includes for 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 15m (15ft). The UV sensor incorporates a special logic circuit to help prevent false alarms caused by solar radiation. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal. The Mini series flame detectors are ideal for indoor applications in locations such as transport terminals, storage areas, industrial kitchens and historical and cultural sites with large open areas, providing an efficient alternative smoke and heat detectors often prove to be ineffective.
