61-6647 Fireye Outer Assembly

Overview

The Fireye 61-6647 is a 3-foot (914 mm) outer carrier assembly designed for use with Fireye fiber optic flame scanner systems, such as the InSight II. It serves as a protective permanent housing for fiber optic inner carrier assemblies (glass or quartz) in industrial burner environments where a direct line of sight to the flame is obstructed by internal burner components. This assembly is part of a modular system that includes the outer carrier, an inner carrier bundle, and a scanner electronics assembly.

Features

• Provides a rigid and flexible stainless steel protective conduit for delicate fiber optic bundles.
• Designed to be permanently fastened to the boiler or burner housing.
• Compatible with both quartz and glass fiber optic inner carrier assemblies.
• Enables flame monitoring in challenging environments with moving vanes or air compartments.
• High-temperature resistant construction suitable for industrial combustion chambers.

Specifications

Applications

The 61-6647 is used in commercial and industrial boiler applications where the target flame may be obscured or moved away from the line of sight of conventional surface-mounted scanners. It is specifically employed in systems utilizing fiber optic light guides to bring flame radiation from the furnace interface to a detector located outside the windbox. It is commonly used in power generation, large-scale HVAC, and process heating industries.
