The Fireye 61-7209-9 is a 9-foot (2.7 meters) quartz inner carrier assembly designed for use with Fireye’s InSight II and Series IV flame scanners in industrial burner applications. This assembly is part of a fiber optic system that enables flame monitoring in environments where direct line-of-sight is obstructed or where burner components are subject to movement.
Key Features:
-
Quartz Optics: Utilizes high-temperature quartz materials capable of withstanding temperatures up to 752°F (400°C) at the “hot” end, ensuring durability in demanding conditions.
-
Flexible Design: Incorporates a flexible stainless steel tubing, allowing the assembly to accommodate burner movements and thermal expansion without compromising the integrity of the fiber optics.
-
Cooling Air Inlet: Equipped with a 3/8-inch NPT cooling air inlet to maintain optimal operating temperatures and prevent overheating of internal components.
-
Secure Mounting: Features a flange mounting plate for stable and secure attachment to the burner assembly, ensuring precise alignment and reliable flame detection.
