61-7080-3 Fireye Inner Assembly

Overview

The Fireye 61-7080-3 is a 3-foot (914 mm) inner carrier assembly specifically designed for use with Fireye InSight series flame scanners. It serves as a critical internal component of a fiber optic scanner system, designed to transmit light from the burner flame to the scanner electronics. This assembly features a quartz fiber optic bundle, which is optimized for detecting ultraviolet (UV) radiation, making it ideal for monitoring gas-fired burners where high-temperature performance and precise flame discrimination are required.

Features

• High-quality quartz fiber optic bundle for superior UV light transmission.
• 3-foot (914 mm) nominal length suitable for specific burner geometries and windbox depths.
• Engineered for industrial environments with high-temperature resistance.
• Compatible with InSight I and InSight II integrated flame scanner models.
• “Hot” and “cold” ends clearly marked on ferrules to ensure correct orientation during installation.
• Durable stainless steel construction for the carrier housing.

Specifications

• Part Number: 61-7080-3
• Nominal Length: 3 feet (914 mm)
• Optical Material: High-temperature quartz
• Compatible Scanners: Fireye InSight (e.g., 95IR, 95UV, 95DS, 95DSS3)
• Compatible Outer Carrier: Typically 61-6647 (nominal 3 ft)
• Operating Environment: High-temperature industrial burner applications

Applications

The 61-7080-3 inner carrier assembly is used in industrial and commercial combustion systems where a standard surface-mounted scanner cannot achieve a clear line of sight to the flame. It is commonly applied in boilers with movable vanes, air compartments, or complex burner nozzles. By utilizing the fiber optic bundle, the assembly brings flame radiation from the harsh environment near the burner to the scanner electronics located safely outside the windbox. It is primarily used in gas-fired applications due to its quartz construction but is also effective for coal and oil flames.
