Overview
The FD1-UVIR2 Explosion-Proof Flame Detector is an advanced UV/IR2 fire detection device engineered for hazardous industrial environments.
It provides high sensitivity to hydrocarbon-based flames while maintaining strong immunity against false alarms caused by sunlight, electrical arcs, and welding sparks.
With dual-spectrum sensors and a 32-bit microprocessor, the FD1-UVIR2 ensures accurate, fast, and stable performance under harsh operating conditions.
Constructed from corrosion-resistant cast aluminum with IP66 protection and Ex db IIC T6 Gb / Ex tb IIIC T80°C Db explosion-proof certification, it delivers unmatched reliability for oil, gas, and chemical safety applications.
