Industrial Four-Band UV/IR Flame Detector with Triple IR and UV Sensor for Hazardous Areas

Our Four-Band UV/IR Flame Detector integrates three infrared sensors and one ultraviolet sensor to deliver precise and reliable fire detection in high-risk industrial settings. Engineered with a proprietary algorithm and robust 316L stainless steel housing, this detector excels in extreme conditions, including strong acids, alkalis, and wide temperature variations. Its modular core design simplifies maintenance, while advanced EMC circuitry ensures superior electromagnetic immunity. With a wide 120° viewing angle and support for multiple fuel types, this detector meets GB12791, GB15631, and GB3836 standards, making it an ideal choice for oil, gas, chemical, and other hazardous industries.
