61-6872-6 Fireye Fiber Optic

Overview

The Fireye 61-6872-6 is a premium 6-foot (1829 mm) quartz fiber optic bundle designed for industrial flame monitoring in challenging environments. It is engineered to transmit flame radiation from the burner area to a remotely located flame scanner, particularly in applications where the line of sight is obstructed by burner components or where high temperatures prohibit direct mounting of electronic equipment. The quartz construction ensures high-temperature resistance and reliable signal transmission for both ultraviolet (UV) and infrared (IR) flame signatures.

Features

• High-Temperature Quartz Optics: Utilizes specialized quartz fibers capable of withstanding extreme temperatures at the burner interface.
• Flexible Protection: Enclosed in a series of flexible stainless steel tubes to protect the delicate fiber bundle from mechanical damage and environmental stress.
• Directional Orientation: Features clearly marked “hot” (H) and “cold” (C) ends to ensure proper installation, with a blue marker indicating the cold end for easy identification.
• Durable Construction: Built with 303 stainless steel mounting heads and flexible stainless steel outer carriers to ensure longevity in industrial boiler and furnace environments.
• Optimized Signal: Designed to bring flame radiation to the detector with minimal loss, even in complex burner configurations.

Specifications

• Part Number: 61-6872-6
• Nominal Length: 6 feet (1829 mm)
• Fiber Material: High-temperature quartz
• Max Temperature (Hot End): 752°F (400°C)
• Outer Diameter: Approximately 1.3 inches (33 mm) for the stainless steel housing
• Weight: Approximately 1.0 lbs (0.45 kg)
• Compatibility: Designed for use with Fireye InSight II, 95UV, 85UV, and 45UVFS scanners.

Applications

The Fireye 61-6872-6 is primarily used in commercial and industrial boiler applications where moving vanes, air compartments, or burner nozzles obscure the target flame from conventional surface-mounted scanners. It is ideal for monitoring individual burner flames within a furnace fireball, provided ignition occurs before entering the main furnace area. Common installations include power plants, large-scale manufacturing facilities, and any combustion system where high-ambient heat or physical obstructions require the scanner electronics to be mounted externally to the burner windbox.
