Product Description

The ABB SF810-LOS-IR-T-C-W is a high-precision Multi-Flame Infrared Scanner engineered for complex industrial and utility boiler applications. Part of ABB’s SF810 series, this sensor monitors flame presence and quality across multiple burners, supporting fuels such as heavy oils, coal, natural gas, and coke oven gas.

Housed in a robust weatherproof enclosure, the SF810 combines infrared sensing and digital signal processing to reliably detect flames while filtering out background radiation and spurious heat sources.

Key Features

• Infrared Flame Detection: Detects flame radiation across 700–3300 nm, making it ideal for hydrocarbon and solid fuels.

• Advanced Signal Processing: Frequency-based DSP differentiates between target flames and background heat, minimizing false alarms.

• Integrated User Interface: Rear-mounted display and keypad allow flame intensity visualization and parameter adjustments directly on-site.

• Dual Output Signals: Provides 4–20 mA analog output for continuous monitoring and dry relay contacts for BMS integration.

• Rugged Construction: IP66/IP67 rated stainless steel or aluminum housing protects against dust, moisture, and harsh plant conditions.

• Continuous Self-Test: Built-in diagnostics ensure reliable operation with rapid flame failure response.

Technical Specifications
