61-3263-1 Fireye Assembly

Overview

The Fireye 61-3263-1 is a shutter bracket and lens assembly designed specifically for use with 45UV5 series self-checking ultraviolet flame scanners. This essential maintenance and replacement kit ensures the proper mechanical operation of the scanner’s self-checking mechanism, which is critical for industrial burner systems that operate continuously. It includes the necessary hardware to facilitate accurate flame detection while protecting the internal sensor components from the combustion environment.

Features

• Integral Shutter Mechanism: Enables the self-checking functionality by periodically blocking the UV tube’s line of sight to verify electronic and sensor integrity.
• Planoconvex Quartz Lens: Features a high-quality quartz lens designed to focus and maximize ultraviolet radiation sensitivity for reliable flame monitoring.
• Comprehensive Kit: Includes the shutter bracket, lens holder, gaskets, and the 61-2914 shutter assembly for a complete installation.
• Durable Construction: Engineered with high-temperature, oil-resistant gaskets and robust housing components to withstand harsh industrial boiler and furnace environments.
• Easy Maintenance: Designed for straightforward replacement to minimize downtime during routine scanner servicing.

Specifications

• Model Number: 61-3263-1
• Compatible Scanners: Fireye 45UV5-1005, 45UV5-1006, 45UV5-1007, 45UV5-1008, 45UV5-1009, and 45UV5-1105
• Components Included: Shutter assembly (61-2914), lens, lens holder, bracket, and gaskets
• Temperature Rating: Designed to operate within the 45UV5 scanner’s ambient range of -40 degree F to 200 degree F (-40 degree C to 93 degree C)
• Material: High-temperature quartz (lens) and industrial-grade metals/gaskets

Applications

The 61-3263-1 assembly is used as a replacement part for Fireye 45UV5 self-check scanners integrated into industrial burner management systems. It is primarily utilized in large-scale commercial and industrial boilers, kilns, and furnaces firing natural gas, oil, or other fossil fuels. The assembly is vital for systems requiring continuous flame monitoring, where the scanner must perform internal safety checks without cycling the burner off.
