ABB SF810-FOC-IR-TL Flame Scanner Head

The ABB SF810-FOC-IR-TL, cataloged here as the SF810-FOC-IR-TL 3/4-Inch Threaded Scanner Head, operates as a high-precision, field-level optical component for localized infrared (IR) radiation monitoring within industrial burner management and boiler safety networks.

Hardware Specifications

Burner Management and Safety System Interface

This specific 3/4-inch threaded variant of the SF810 series installs directly onto standard boiler sight tubes or matching fiber optic guide assemblies. The onboard infrared sensor captures the high-frequency flicker and dynamic amplitude profiles of gas, oil, or coal flames, converting optical light patterns into low-voltage signals for remote amplification. This physical routing bypasses local processing latencies, ensuring that real-time flame state updates reach the primary Burner Management System (BMS) synchronously. The hardware configuration provides seamless integration across modular I/O density scaling frameworks, maintaining stable connection tracking and complete compatibility over deterministic industrial networks while filtering out deceptive background radiation from surrounding burner zones.

Frequently Asked Questions

Q: What are the installation advantages of the 3/4-inch threaded mounting interface?

A: The 3/4-inch threaded design allows the optical scanner head to screw directly into standard industrial sight pipes or specialized air-purged packing glands, establishing a sealed, secure mechanical connection that prevents combustion gas leaks.

Q: Does this specific US-sourced scanner head require an external amplifier card?

A: Yes. The SF810-FOC-IR-TL is a raw optical/sensor head configuration. It must be paired with a compatible remote ABB flame switching amplifier unit (such as the safe-shutter control modules) to translate the raw IR current signals into discrete safety-relay contacts.
