Product Description

The ABB SF810INT-FOC-UV-T-L is a high-reliability ultraviolet (UV) flame scanner engineered for industrial burners operating under extreme conditions. Part of the Uvisor™ SF810 series, this model incorporates a fiber optic sensor head connected to robust electronics, enabling precise flame monitoring in hard-to-access or high-temperature locations.

Key Features

Integrated UV Detection
The SF810INT-FOC-UV-T-L combines a silicon carbide (SiC) photodiode with advanced signal processing for accurate flame recognition. It distinguishes target flames from background radiation or neighboring burners to prevent false alarms.

Fiber Optic Flexibility
The fiber optic configuration allows installation in areas with limited space, high ambient temperatures, or obstructed lines-of-sight, while keeping electronics protected in cooler zones.

Fail-Safe and Diagnostics
Built-in self-checking circuits ensure the unit defaults to “no flame” upon failure. Continuous diagnostics support compliance with safety standards and SIL-rated applications.

Output and Communication
Provides a 4–20 mA analog signal representing flame intensity, a dedicated relay for flame status, and dual RS-485 ports supporting Modbus RTU and Profibus DP-V1 protocols.

Environmental Resistance
The sensing head tolerates temperatures up to 350°C (662°F), while the electronics operate from -40°C to +70°C. IP66-rated housing protects against dust and powerful water jets.

FAQ

Q: Can this scanner detect flames in obstructed or corner-fired burners?
A: Yes. The fiber optic design allows flexible positioning, providing accurate detection even without direct line-of-sight.

Q: What fuels are supported?
A: Gas, oil, and coal. Sensitivity and flame-on/off delays are configurable for each fuel type.

Q: Is the unit SIL-rated?
A: Yes. Designed for SIL3 compliance, including self-diagnostic fail-safe functions.

Q: What environmental conditions can it withstand?
A: The fiber optic tip tolerates up to 350°C, while the electronics are rated for -40°C to +70°C, and the housing is IP66-protected.
