61-2275-2 Fireye LENS Assembly

Overview

The Fireye 61-2275-2 is a high-quality quartz lens assembly specifically designed for use with Fireye 45UV5 series self-checking ultraviolet flame scanners. This essential optical component is engineered to focus ultraviolet radiation from a flame onto the scanner’s internal detector tube, ensuring reliable flame monitoring in industrial burner management systems. The use of quartz allows for superior transmission of ultraviolet light compared to standard glass, making it ideal for detecting emissions from fossil fuel flames such as natural gas, propane, and light oil.

Features

• Quartz Optical Material: Provides optimal transmission of ultraviolet wavelengths (190 to 250 nanometers) for high-sensitivity flame detection.
• Complete Assembly: Includes the lens, lens holder, and retainer for a secure and straightforward installation.
• Planoconvex Design: Features a curved surface that increases the scanner’s sensitivity by concentrating UV energy.
• Durable Construction: Built to withstand the harsh environments of industrial combustion chambers and burner fronts.
• Precise Fit: Specifically engineered as a direct replacement part to maintain the factory performance of Fireye 45UV5 scanners.

Specifications

• Model Number: 61-2275-2
• Material: Quartz (Fused Silica)
• Compatibility: Exclusively for Fireye 45UV5 series scanners (e.g., 45UV5-1005, 45UV5-1007, 45UV5-1009)
• Operating Temperature: Designed to function within the scanner’s range of -40 degree F to 200 degree F (-40 degree C to 93 degree C)
• Components Included: Quartz lens, lens holder, and lens retainer
• Dimensions: Standardized for 1-inch NPT/BSP scanner housings

Applications

The 61-2275-2 lens assembly is primarily used in industrial and commercial boiler applications where Fireye 45UV5 self-checking scanners are employed. It is a critical component for monitoring flames in power plants, large-scale HVAC systems, and manufacturing facilities using gaseous or liquid fuels. Its high UV transparency makes it particularly effective for detecting natural gas, coke oven gas, methane, and kerosene flames, especially in applications where the scanner must be mounted at a distance from the burner.
