Fireye 45UV5-1009 UV Flame Scanner
$1,596.00
The Fireye 45UV5-1009 is a self-checking ultraviolet flame scanner for supervised single-burner boilers, process ovens, and heaters. Its 0.4-second closed and 3.6-second open shutter cycle verifies valid flame signals before the associated Fireye control energizes its Flame Relay.

Description
- Targeted UV Flame Detection: Detects shortwave ultraviolet radiation between 2200 and 2600 Angstroms emitted by gas, oil, and coal flames while filtering out false signals from glowing furnace brickwork.
- Dynamic Self-Checking Operation: Continuously verifies phototube health and signal circuit integrity, making it safe for continuous-duty industrial burners operating 24 hours a day or longer.
- Precision Shutter Cycle Timing: Features an internal mechanical shutter operating on a fixed 0.4-second closed and 3.6-second open cycle to simulate flame-out conditions and test sensor conductivity.
- Internal Shutter Drive Circuitry: Houses shutter drive electronics directly inside the scanner enclosure for reliable, self-contained performance without requiring external timing modules.
- Threaded 1-Inch NPT Sight Mount: Built with a 1-inch NPT threaded connection for direct, secure attachment onto sight pipes and precise alignment with the primary flame root.
- Rugged Industrial Enclosure: Encased in a durable cast aluminum housing engineered to withstand harsh plant conditions, electrical interference, and high ambient operating temperatures.

Description
The Fireye 45UV5-1009 UV Flame Scanner is a self-checking optical flame detector designed for continuous-duty monitoring of industrial gas, oil, and multi-fuel burners. Operating in the 2200 to 2600 Angstrom ultraviolet radiation band, the 45UV5-1009 detects shortwave UV light emitted by active combustion while discriminating against background thermal radiation from hot furnace refractories. Equipped with an internal shutter drive mechanism, the scanner performs automatic self-checking at set intervals (0.4 seconds closed, 3.6 seconds open) to verify proper phototube function and signal circuit integrity without interrupting burner operation. Built with a heavy-duty cast aluminum housing and a standard 1-inch NPT threaded sight connection, the Fireye 45UV5-1009 pairs with compatible Fireye flame safeguard amplifiers and control systems to deliver reliable, fail-safe combustion supervision across industrial boilers, power generation plants, and thermal processing facilities.
Frequently Asked Questions
What makes the Fireye 45UV5-1009 suitable for continuous-duty burner operation?
The 45UV5-1009 includes an internal electromechanical shutter that periodically blocks incoming UV light (0.4 seconds closed, 3.6 seconds open). This dynamic self-check verifies that the UV tube and internal electronics are functioning correctly and have not faulted into a runaway "flame-on" state while the burner continues running.
What spectral range does the Fireye 45UV5-1009 detect?
The scanner is specifically tuned to detect shortwave ultraviolet radiation in the 2200 to 2600 Angstrom (220 to 260 nm) spectrum, which is present in fossil fuel flames but absent from background furnace heat and lighting.
Which Fireye control systems and flame amplifiers work with the 45UV5-1009?
The 45UV5-1009 connects to Fireye Flame-Monitor, BurnerLogix, and 70UV5 series combustion management systems when equipped with self-checking UV flame signal amplifiers such as the 72DUVS or EUVS series modules.
How is the Fireye 45UV5-1009 mounted to a burner sight pipe?
The scanner features a 1-inch NPT threaded female mounting connection that threads directly onto a 1-inch sight tube positioned to view the intersection of the main flame and pilot ignition zone.
What routine maintenance is recommended for the 45UV5-1009 flame detector?
Maintenance involves regularly cleaning the optical quartz lens with a soft, clean cloth, clearing dust or soot from the sight pipe, and verifying shutter motion and flame signal strength on the attached amplifier control unit.
