Description
🔥 Product Overview
The SAACKE FLS 03 is a flame sensor used for flame supervision in SAACKE burner and combustion-control systems. The FLS 03 is part of the SAACKE family of flame sensors and detectors used in marine and industrial combustion equipment.
The sensor provides flame-status information to the associated flame-monitoring or burner-management equipment. It is intended for applications where reliable confirmation of burner flame presence is required during ignition and continuous combustion operation.
The identified FLS 03 is associated with SAACKE part number 2-8453-101879. Because SAACKE installations can use different flame-monitoring arrangements, the exact electrical characteristics and compatible amplifier/controller should be verified against the existing burner documentation before replacement.

🔍 Flame Monitoring Function
The FLS 03 forms part of the flame-supervision chain in a burner system. During normal combustion, the sensor detects the applicable flame condition and provides the corresponding signal to the associated monitoring equipment.
The flame sensor should not be treated as a standalone burner-management controller. The final safety decision is normally performed by the connected flame amplifier, flame detector, burner controller, or safety-control system.
Correct sensor positioning is important. The sensing element must have an appropriate view of the flame while being protected from conditions that could interfere with reliable detection.
🚢 Typical Applications
The FLS 03 can be used in applications such as:
- Marine boiler burner systems
- Steam-generation equipment
- Oil-fired combustion systems
- Industrial heating equipment
- SAACKE burner installations
- Boiler flame supervision
- Burner ignition monitoring
- Flame-failure detection systems
- Legacy marine automation systems
- Industrial combustion equipment maintenance
SAACKE’s FLS product family includes several flame-sensor variants, including FLS 03, FLS 04, FLS 07, FLS 08 and FLS 09 UV-5, so model identification is important when selecting a replacement.
🔌 System Integration
A typical installation can be represented as:
Burner Flame → FLS 03 Sensor → Flame Monitoring / Amplifier → Burner Management System → Fuel Safety Logic
The sensor works as part of this complete protection chain. Problems attributed to the sensor can also originate from the flame amplifier, controller, wiring, sensor alignment, burner condition, or fuel/ignition system.
When replacing an existing FLS 03, the original system drawings should be used to confirm the sensor’s electrical and mechanical arrangement.
🛠️ Installation & Commissioning
Before installation:
- Confirm the sensor model and part number.
- Compare the replacement with the installed FLS 03.
- Verify the associated flame-monitoring device.
- Confirm wiring and terminal identification.
- Isolate the burner system before electrical work.
- Inspect the sensor mounting arrangement.
- Ensure the sensing path is correctly aligned with the burner flame.
- Check for contamination, soot, oil deposits, or mechanical damage.
- Restore the system according to the burner manufacturer’s procedure.
- Perform a controlled flame-establishment and flame-failure test.
Because this component participates in burner safety, commissioning should be performed by qualified personnel familiar with the installed combustion-control system.
🔧 Troubleshooting Guide
No flame signal:
Check sensor alignment, wiring, associated flame amplifier, burner ignition, and actual flame condition.
Intermittent flame signal:
Inspect the sensing surface and optical path for contamination and verify that vibration or burner movement has not changed sensor alignment.
Flame detected incorrectly:
Check sensor positioning and the associated monitoring circuit. Unwanted radiation or an incorrectly positioned sensor may affect flame supervision.
Burner trips after ignition:
Confirm that the flame is established correctly and that the sensor provides a stable signal to the flame-monitoring equipment.
Replacement sensor does not operate:
Verify the exact FLS model and part number. SAACKE uses several flame-sensor variants, and visually similar units should not be substituted without compatibility verification.
🧰 Maintenance
Regular inspection is recommended for flame sensors installed near combustion equipment.
Check:
- Sensor mounting
- Wiring and terminals
- Sensing surface
- Cable insulation
- Sensor alignment
- Burner flame stability
- Flame-monitoring signal
- Associated amplifier/controller
- Heat and vibration exposure
- Contamination from soot or combustion products
A clean sensing path and stable mechanical mounting are particularly important for consistent flame supervision.
🔄 Replacement Considerations
The FLS 03 should be replaced with a unit matching the original system configuration. Verify:
- Model: FLS 03
- Part number: 2-8453-101879
- Sensor type
- Associated flame amplifier or detector
- Wiring
- Mechanical mounting
- Burner type
- Flame-monitoring logic
Do not automatically substitute an FLS 04, FLS 07, FLS 08, FLS 09 UV-5, or another SAACKE sensor simply because the physical appearance is similar. Different sensor technologies and associated monitoring arrangements may require different system configurations.
❓ FAQ
What is the SAACKE FLS 03?
It is a flame sensor used for burner flame supervision in SAACKE combustion systems.
What is the part number?
The identified part number is 2-8453-101879.
Is the FLS 03 a complete flame-monitoring controller?
No. It is a sensing component that works with the associated flame-monitoring or burner-management equipment.
Where is the FLS 03 used?
