D-LE 103
Optical flame sensor
UV, VIS or IR flame sensor for combination with a control unit or burner control. For monitoring gas, oil and coal flames, particularly at single burner plants.
Functionality: Optical flame monitoring
Features
- Flame sensor for every spectral flame monitoring range from UV to IR
- Self-monitoring and fail-safe in conjunction with a control unit / burner control
- Connection to the D-UG 120, D-UG 660 control units and D-GF 150(-MB) burner control
- Uniform electrical connection and connection to the combustion chamber, making all flame sensors interchangeable
Benefits
- Compact design also allows use in confined spaces
- Selection of the available detectors allows the monitoring of flames of all fuels within the same device family
- Device technology proven thousands of times over
Applications
- Simple combustion plants with single burners or optically separated burners
- Combustion processes in continuous operation
- Applications with confined space at the burner plate
