45UV5-1105 Fireye Scanner

Overview

The Fireye 45UV5-1105 is a self-checking ultraviolet (UV) flame scanner designed for industrial burner management and flame safeguard applications. It is engineered to detect UV radiation emitted from fossil fuel flames while providing continuous electronic self-checks to ensure the integrity of the sensing tube and circuitry. This model features a 1-inch BSP mounting thread and comes with an 8-foot factory-prewired lead, making it a robust solution for monitoring burners that operate for long periods without cycling.

Features

• AutoCheck Self-Testing: Integrated electromagnetic shutter performs an automatic self-test every 4 seconds to verify the functionality of the UV tube and internal electronics.
• UV-Only Sensitivity: Responds only to ultraviolet radiation in the 190 to 250 nanometer range, ensuring it is not affected by background infrared or visible light.
• Pre-Wired Leads: Equipped with an 8-foot (2.4m) 4-wire cable (two for shutter, two for signal) to simplify electrical connections and reduce field installation time.
• Durable Construction: Housed in a die-cast aluminum casing with high-temperature oil-resistant gaskets, rated for NEMA 4X / IP66 environments.
• Easy Maintenance: Features a hinged mounting flange that allows for quick access to the lens for cleaning without removing the entire scanner.

Applications

The 45UV5-1105 is designed for use with Fireye flame safeguard controls, specifically compatible with the P-Series, BurnerLogix, Flame-Monitor, D-Series, MicroM, and FlameWorx systems. It is ideally suited for monitoring flames from fossil fuels such as natural gas, propane, methane, butane, kerosene, and diesel. Because of its self-checking capabilities, it is the standard choice for continuous-duty burners found in industrial boilers, process ovens, furnaces, and large utility boilers where the flame is monitored for 24 hours or longer.
