Industrial UV/IR Flame Detector with Triple IR and UV Sensor for Explosive Environments

The Industrial UV/IR Flame Detector combines three infrared sensors and one ultraviolet sensor to deliver highly reliable flame detection across a wide spectral range. Designed for challenging environments, this detector uses proprietary algorithms and optical filters to minimize false alarms while maximizing detection accuracy. Its robust aluminum housing ensures durability, and support for multiple communication protocols (relay, 4-20mA, RS485) offers flexible integration. Ideal for oil, gas, chemical, and other high-risk industries, this detector meets GB12791, GB15631, and GB3836 standards, providing peace of mind in explosive atmospheres.
