Overview

The SF810INT-LOS-UV-T-C-W is part of ABB’s advanced Uvisor SF810i flame scanner family, combining the strengths of the Uvisor and Safe Flame DFS product lines. This model is specifically engineered for line-of-sight (LOS) applications, using ultraviolet (UV) sensing technology to detect flame presence and quality in multi-fuel burners.

It is ideal for utility and industrial boilers, where consistent flame verification is critical for safety and efficiency. The unit features self-diagnostics, temperature compensation, and fail-safe operation, ensuring dependable performance even in high-temperature, high-vibration environments.

Moreover, the SF810INT-LOS-UV-T-C-W supports multiple communication protocols and integrates easily with distributed control systems (DCS), making it suitable for both new installations and retrofit projects.

Technical Data

Typical Applications

The SF810INT-LOS-UV-T-C-W is widely used in:

• Utility boilers for flame monitoring across large burners

• Industrial furnaces requiring high-speed flame detection

• Waste-to-energy plants with variable fuel compositions

• Petrochemical and refining facilities with safety-critical combustion zones

For instance, in a multi-burner coal-fired boiler, this flame scanner ensures each burner maintains a stable flame, preventing fuel-rich conditions and unburned emissions. Its UV detection is immune to visible light interference, making it ideal for high-glare environments.
