FD02-UVIR3 UV/IR Flame Detector with Weather Protection Cover

Product Description
The ANWETECH FD02-UVIR3 is a point-type UV/IR flame detector developed for rapid and dependable detection of open flames in industrial environments. It combines an infrared sensor and a solar-blind ultraviolet sensor with integrated signal processing to improve flame detection performance while enhancing immunity to false alarms.

The detector is designed for hazardous areas and features an explosion-proof aluminum alloy enclosure with IP66 / IP67 protection. It operates on 24 VDC and provides both relay output and 4-20 mA current loop output for easy integration with fire alarm panels, control systems and industrial monitoring systems.

With a wide 120° field of view and long detection distance for multiple fuels, the FD02-UVIR3 is suitable for applications such as petrochemical facilities, oil depots, gas stations, chemical plants, storage areas and other locations where reliable flame detection is required.
