Overview
The FD1-UVIR3 Explosion-Proof Flame Detector is a premium triple-spectrum flame detector combining ultraviolet (UV) and triple-infrared (IR3) sensing technologies.
It offers outstanding flame recognition accuracy, rapid response, and excellent resistance to false alarms caused by sunlight, welding, hot surfaces, or electrical arcs.
Designed for hazardous industrial environments, this detector is equipped with a built-in 32-bit microprocessor and advanced flame recognition algorithm, ensuring intelligent analysis of flame signals and real-time status monitoring.
Constructed from corrosion-resistant aluminum alloy with IP66 protection and Ex db IIC T6 Gb / Ex tb IIIC T80°C Db explosion-proof certification, the FD1-UVIR3 ensures long-term reliability under extreme conditions.
It is ideal for oil & gas plants, petrochemical sites, offshore platforms, and power generation facilities.
Triple-Spectrum Detection (UV + IR3): Combines ultraviolet and three infrared sensors for superior flame identification.
High Immunity to False Alarms: Effectively filters out sunlight, welding arcs, and hot object interference.
