Overview
The Fireye 85UVF1-1QD is a microprocessor-based integrated flame scanner designed for reliable detection and monitoring in industrial combustion applications. Powered by 24 VDC and featuring an 8-pin electrical quick-disconnect (QD) connector, this UV scanner provides straightforward installation and maintenance. The scanner’s solid-state ultraviolet sensor operates within the 295–340 nanometer wavelength range, detecting flame amplitude modulations (“flicker”) across a wide frequency spectrum to ensure consistent, accurate performance.
Key Features
- Microprocessor-based design with automatic learning and self-diagnostics for operational integrity
- Integrated internal flame relay with automatically set ON/OFF thresholds—no external amplifier required
- 4–20 mA analog output for real-time flame strength monitoring and data logging
- 8-pin quick-disconnect (QD) electrical connector for simplified installation and rapid field replacement
- Solid-state UV sensor covering 295–340 nm spectral range for reliable ignition and flame monitoring
- Cast aluminum housing with gray polyester powder coat; IP66 ingress protection with 0.4-joule impact rating
