The FD01-IR3 Explosion-Proof Flame Detector is a high-performance triple-infrared (IR3) detector designed for fast, reliable flame recognition in hazardous and industrial environments.
It utilizes three infrared sensors and advanced digital signal processing to accurately identify the spectral signature of real flames while rejecting false alarms caused by sunlight, reflections, welding, and hot surfaces.
Built with a cast-aluminum explosion-proof enclosure and rated IP66, the FD1-IR3 ensures long-term durability, stability, and corrosion resistance in harsh conditions such as oil & gas fields, chemical plants, and storage facilities.
