SAACKE FLS 08 Flame Sensor 2-8453-076322

SAACKE FLS 08 Flame Sensor and Detectors 2-8453-076322 FLS08 (New)

The SAACKE FLS 08 Flame Sensor (MPN: 2-8453-076322) is a precision-engineered, high-reliability electronic flame scanner built specifically for heavy-duty industrial and marine combustion systems. Designed to monitor burner flames continuously, this unit provides real-time optoelectronic feedback to the burner management system (BMS), ensuring instantaneous trip sequences in the event of flame failure. Supplied in Brand New condition, this sensor guarantees optimal spectral sensitivity, fail-safe operation, and long-term durability in harsh marine environments.

Key Features

1. Continuous Self-Monitoring: Incorporates internal diagnostic routines to verify electronic integrity and sensor window cleanliness without manual intervention.
2. High Discriminative Sensitivity: Accurately distinguishes between actual burner flame radiation and background refractory glow.
3. Rugged Industrial Build: Encased in an IP65-rated housing designed to withstand severe vibrations, thermal shocks, and ambient moisture found in ship engine rooms.
4. Fast Response Time: Delivers millisecond-level signal switching to protect against unburnt fuel accumulation in the combustion chamber.
5. Plug-and-Play Compatibility: Features standardized terminal allocations and mounting interfaces for direct drop-in replacement on existing Saacke burner assemblies.

Compatible Equipment Models

• SAACKE Rotary Cup Burners (SKV series)
• SAACKE Steam and Hot Water Boiler Combustion Lines (DDZ / Type COMPACT)
• Burner Management Systems (BMS) utilizing 24V DC discrete safety interlocks

Applications

• Marine auxiliary and main propulsion boilers
• Offshore oil and gas production platform heaters
• Industrial steam generation plants and thermal fluid heaters
• Refinery process furnaces utilizing heavy fuel oil (HFO) or marine gas oil (MGO)

Marine Engineer Expert’s Guide

• Alignment and Sight Tube Purging: When installing the FLS 08, ensure the optical sight tube is clean and unobstructed. Connect the purging air line correctly; a positive pressure purge prevents soot, oil mist, and carbon deposits from clouding the sensor lens during heavy fuel oil combustion.
• Electrical Screening: Always use shielded multi-core cables for the 24V DC supply and relay output loops. Run sensor wiring away from high-voltage ignition transformer cables and variable frequency drives (VFDs) to prevent electromagnetic interference (EMI) tripping the burner safety loop.
• Routine Maintenance Check: Periodically check the flame intensity signal output (if routed to a PLC/DMI meter). A gradual degradation in signal strength usually indicates lens contamination or burner misalignment rather than sensor electronic failure.

Frequently Asked Questions

What is the primary function of the SAACKE FLS 08 Flame Sensor?

The FLS 08 continuously monitors the radiation spectrum of the burner flame, converting optical data into an electrical signal to verify stable combustion for the burner management system.

Is this unit supplied as brand new?

Yes, this specific unit (Part Number 2-8453-076322) is supplied strictly in New condition, ready for immediate classification-compliant installation.

Can the FLS 08 handle both oil and gas flames?

Yes, depending on the optical configuration and spectral tuning, it is engineered to reliably detect combustion across multiple fuel types, including marine gas oil, heavy fuel oil, and industrial gases.

What tools or parameters are required during replacement?

Ensure power to the Burner Management System (BMS) is completely isolated (Lockout/Tagout) before disconnecting the plug connector or terminal wiring. Verify optical alignment precisely using the sighting bracket during reassembly.
