45UV5-1000EX Fireye HOUSING & Scanner

Overview

The Fireye 45UV5-1000EX is a self-checking ultraviolet (UV) flame scanner integrated into a heavy-duty, explosion-proof housing. Designed for high-reliability industrial applications, this unit detects UV radiation emitted by fossil fuel flames such as natural gas, propane, and diesel. The “EX” designation indicates the inclusion of a NEMA 7 rated enclosure, making it suitable for hazardous locations where flammable gases or dusts may be present. It features an internal electromagnetic shutter that provides continuous self-checking of the scanner’s internal components and signal circuits, ensuring fail-safe operation in continuous-firing burner environments.

Features

• Self-Checking Technology: Integrated electromagnetic shutter periodically interrupts the UV path to verify proper sensor and circuit operation.
• Explosion-Proof Enclosure: NEMA 7 rated housing designed for Class 1, Div 1 & 2 (Groups C, D) and Class 2, Div 1 & 2 (Groups E, F, G) hazardous environments.
• High Sensitivity Optics: Features a planoconvex quartz lens that increases UV sensitivity by up to 400 percent compared to standard windows.
• Durable Construction: Cast aluminum housing sealed with high-temperature, oil-resistant gaskets for protection in harsh industrial settings.
• Easy Maintenance: Hinged mount design allows for quick access to clean the quartz lens without complete disassembly.
• Purge Air Connection: Includes a 3/8 inch NPT threaded connection for cooling and cleaning the lens with purge air.

Applications

The 45UV5-1000EX is primarily used for flame failure protection in single and multi-burner industrial applications. It is ideal for electric utility boilers, power boilers, large furnaces, and incinerators that operate continuously. It is specifically designed for use in hazardous areas where explosion-proof equipment is mandated. This scanner is highly effective at monitoring flames from natural gas, coke oven gas, propane, methane, butane, kerosene, and light petroleum distillates. In multi-burner setups, it is used to discriminate between the target burner flame and background radiation from adjacent burners.
