ABB SF810-F0-G-2400-N Fiber Optic Cable: Technical Specifications and Industrial Combustion Applications

However, placing highly sensitive electronic sensors directly at the burner front is impossible due to extreme temperatures, soot accumulation, and intense physical vibration. This is where high-durability light guides become essential. The ABB SF810-F0-G-2400-N (also referred to in inventory systems as SF810-F0-G-2400-N\2400) is an industry-leading fiber optic inner assembly engineered to transmit critical flame flicker frequencies from the furnace core to the scanner electronics.
At Wuhan Yuli Automation Technology Co., Ltd., we provide premium, factory-original automation components to maintain plant uptime. This technical guide outlines the engineering specifications, structural advantages, and preventative maintenance strategies for the ABB SF810-F0-G-2400-N fiber optic assembly.
Technical Specifications: Decoding SF810-F0-G-2400-N
ABB’s part numbering system provides field engineers with the exact mechanical and optical configuration of the assembly:
SF810 Series: Built specifically for seamless mechanical and optical alignment with ABB’s SF810 family of intelligent multi-flame scanners.
F0-G: Indicates the premium grade of the optical glass fiber core bundle, optimized for low-loss transmission of specific light frequencies, including Ultraviolet (UV) and Infrared (IR) spectrums.
2400 / \2400: Specifies the exact nominal length of the fiber bundle—2400 mm (2.4 meters). This length is ideal for deep-reach windbox installations, allowing the viewing head to sit close to the fuel nozzle while keeping the scanner body outside the heat zone.
N: Denotes the specialized heavy-duty end fittings and protective industrial cladding, designed to lock securely into standard ABB outer guide pipe assemblies.
Core Engineering Advantages of the ABB 2400mm Fiber Optic Assembly
1. High-Temperature Optical Isolation
The combustion zone of a fossil-fuel burner can easily exceed 1000°C, a temperature that would immediately destroy standard semiconductor sensors. The raw, high-purity glass fibers within the SF810-F0-G-2400-N possess exceptional thermal stability. By isolating the electronics from the thermal stress of the burner wall, the system ensures continuous, uninterruptible flame monitoring.
2. Low Attenuation and Frequency Precision
Intelligent flame scanners like the SF810 do not just measure light intensity; they analyze the micro-pulsations (flicker frequency) of the flame root to distinguish a specific burner from background furnace reflection. The premium glass manufacturing process used in this cable minimizes signal attenuation across its 2.4-meter length. This guarantees that the precise flicker signature reaches the microprocessor without distortion, preventing false safety trips.
3. Industrial Grade Mechanical Armoring
The external environment of an industrial boiler is prone to mechanical movement, high ambient dust, and chemical exposure. The SF810-F0-G-2400-N is jacketed in a rugged, flexible conduit armor that shields the brittle inner glass cores from mechanical shearing, kinking, and environmental contamination.
Field Maintenance and Installation Best Practices
To ensure long-term operational reliability and prevent unexpected plant outages, maintenance engineers should strictly adhere to the following guidelines:
1. Observe the Minimum Bend Radius
While the armored outer conduit is flexible, the inner glass fibers are structurally brittle. During installation or MRO replacement, never force the cable into a tight angle. Exceeding the manufacturer’s specified minimum bend radius will cause internal micro-fractures in the glass strands. This permanently degrades the signal margin, leading to intermittent "No Flame" faults on the control panel.
2. Maintain Continuous Purge Air Supply
Soot, slag, and unburnt fuel oil will rapidly cloud the fiber optic lens if left unprotected. The outer guide pipe must be supplied with a continuous stream of clean, dry, oil-free instrument air. This positive pressure creates an aerodynamic barrier at the lens tip, sweeping away particulates and keeping the optical path unobstructed.
3. Routine Outage Cleaning
During planned boiler shutdowns, carefully extract the fiber optic inner assembly. Inspect the lens face for any heat discoloration or residue build-up. Clean the glass surface using a lint-free optical wipe dampened with pure industrial isopropyl alcohol. Inspect the length of the conduit for any signs of physical crushing or thermal breakdown.
