Fireye 46-185 Magnifying Lens Assembly

The Fireye 46-185 Magnifying Lens Assembly is a critical optical component engineered to enhance the signal response of UV7 ultraviolet flame scanners. By utilizing a high-grade 46-186 quartz magnifying lens, this assembly focuses and amplifies the UV radiation emitted from the flame, significantly increasing the sensitivity of the sensor. This is particularly vital in industrial combustion systems where the burner geometry or long sight pipes may otherwise result in a weak or marginal flame signal. The assembly features a 1/2" F.N.P.T. insulated coupling, which provides a thermal break to protect the scanner from high ambient temperatures and helps prevent electrical noise interference. Integrating this OEM Fireye part into your burner management system ensures reliable flame verification, reducing nuisance shutdowns and maintaining the precise optical focus required for high-performance flame safeguard operations. It is compatible with MB and SB series controls and is built to withstand the demanding environments of boiler and burner monitoring.

• Enhanced Signal Sensitivity: The 46-186 quartz lens magnifies the flame image, allowing the UV7 scanner to detect and verify flames more accurately at greater distances.
• Integrated Thermal Protection: Includes a 1/2" F.N.P.T. insulated coupling that safeguards the scanner electronics from heat conducted through the sight pipe.
• Increased System Reliability: Improves flame detection accuracy in industrial boilers and furnaces, minimizing false readings and downtime.
• Durable Industrial Construction: Designed with high-quality materials to provide long-term performance in harsh burner environments.
• Precise Optical Alignment: Ensures the scanner maintains a clear and unobstructed view of the flame for consistent monitoring.

• Which flame scanners are compatible with the Fireye 46-185? This assembly is specifically designed for use with the Fireye UV7 series, including the UV7A4, UV7R4, and UV7SC scanners.
• How does the magnifying lens improve flame detection? The lens increases the amount of UV radiation reaching the sensor, which is essential for applications with low signal intensity or small pilot flames.
• Does this assembly help with high-temperature applications? Yes, the insulated coupling included in the 46-185 assembly is intended to provide a thermal barrier between the hot burner front and the scanner.
