ABB SF810-LOS-IR-T-C-W | Flame Scanner | Infrared | Industrial Burners & Boilers

Product Description:

The ABB SF810-LOS-IR-T-C-W is a high-performance Flame Scanner from the SF810 series, specifically designed for monitoring and protecting industrial burners and utility boilers. Utilizing Infrared (IR) technology, this scanner detects flames by analyzing the specific flicker frequencies associated with the combustion process, providing critical real-time feedback to optimize burner operation and safety.

Unlike older systems that require separate amplifiers, the SF810-LOS-IR-T-C-W integrates both the sensor and signal processing electronics into one rugged housing, reducing installation complexity and improving reliability. This all-in-one design simplifies system setup while ensuring precise flame detection in challenging conditions such as high dust, smoke, or heavy fuel combustion.

Key Features:

1. Advanced Frequency Discrimination
   The SF810-LOS-IR-T-C-W uses advanced frequency-based discrimination, allowing it to differentiate between the target flame and surrounding background radiation. It is specifically tuned to detect the flicker frequency of the flame, ensuring that the system only responds to the intended burner flame and ignores interference from adjacent flames or hot surfaces.

2. Dual-Channel Signal Processing
   This scanner employs dual-channel analysis, processing both the AC (flicker frequency) and DC (average intensity) components of the infrared signal. This ensures higher accuracy in flame detection and significantly reduces the chance of false flame readings, preventing dangerous situations such as fuel-rich conditions or unintentional burner shutdowns.

3. Built-in Self-Checking Mechanism
   The W configuration of this model includes an internal electronic shutter, or self-check mechanism. This periodically simulates a "no flame" condition to verify that the system is functioning correctly and that the sensors and relays are operating properly. This feature ensures compliance with Safety Integrity Level (SIL) requirements, enhancing the system's reliability and safety.

4. Integrated Display and Controls
   The rear panel of the scanner is equipped with a local user interface (LUI), allowing operators to monitor the flame intensity and adjust settings such as gain and flame-on/off thresholds directly, without the need for a laptop or remote device.

5. Rugged Design with IP66 Rating
   Built for tough industrial environments, the SF810-LOS-IR-T-C-W features an IP66 / NEMA 4X rated housing, ensuring that it is dust-tight and water-resistant. The module operates in extreme temperature conditions, from -40°C to +85°C (-40°F to +185°F), making it ideal for diverse and harsh industrial applications.

6. RS-485 Communication and Remote Diagnostics
   The SF810-LOS-IR-T-C-W supports RS-485 communication via Modbus, allowing remote tuning and diagnostics. This feature is essential for large, complex installations, enabling technicians to perform configuration adjustments and troubleshooting without needing to be physically present.

Frequently Asked Questions (FAQ):

Q: How does the SF810-LOS-IR-T-C-W differentiate between the target flame and other radiation sources?
A: The SF810-LOS-IR-T-C-W uses frequency-based discrimination, specifically targeting the flicker frequency of the primary flame and filtering out other heat sources like refractory bricks or adjacent flames.

Q: What is the benefit of the self-checking mechanism included in this model?
A: The self-checking mechanism periodically simulates a "no flame" condition, ensuring that the scanner is working properly. This self-diagnosis helps meet Safety Integrity Level (SIL) standards and prevents false readings.

Q: Can the SF810-LOS-IR-T-C-W be used in high-temperature environments?
A: Yes, the SF810-LOS-IR-T-C-W operates in extreme temperatures ranging from -40°C to +85°C (-40°F to +185°F), making it suitable for industrial applications that experience high heat.
