Siemens Combustion QRA2(1) UV Detector
The Siemens Combustion QRA2(1) UV Detector is a high-performance ultraviolet flame sensor designed specifically for the supervision of gas and oil flames in industrial and commercial burner systems. Engineered for intermittent operation, this normal sensitivity detector utilizes a side-viewing photodiode to monitor UV radiation in the 190 to 270 nm spectral range. The QRA2(1) features a specialized metallized plastic housing that effectively prevents static charging from fan air flow, ensuring consistent signal integrity during critical ignition spark proving sequences. This model comes factory-equipped with a securing flange and clamp, facilitating direct, secure mounting to the burner. Compatible with a broad range of Siemens burner controls—including the LME, LFL, LMV, and LGB series—this UV flame detector is a standard-issue component for contractors maintaining complex combustion equipment. Capable of supervising both yellow and blue-burning oil flames, the QRA2(1) provides precise flame safeguarding and reliable signal transmission for HVACR burner maintenance and OEM applications.
Key Benefits for the Technician- Broad Compatibility: Seamlessly integrates with Siemens burner controls such as the LME21, LMV5, and LFL series for streamlined field replacement.
- Static Protection: The metallized housing mitigates interference from high-velocity burner fans, protecting the flame signal from electrical noise.
- Ready for Install: Includes the essential securing flange and clamp, reducing the need for separate hardware orders during installation.
- Versatile Supervision: Reliably detects UV radiation from gas burners, oil-fired systems, and ignition sparks, ensuring comprehensive combustion monitoring.
- Can this be used for continuous burner operation? No, the QRA2(1) is rated for intermittent operation only. For continuous processes, a self-checking detector like the QRA5 series is typically required.
- How do I test the signal strength in the field? Use a micro-ammeter (DC) with an internal resistance of ? 5000 ? connected across the appropriate adapter to verify the required detector current for your specific controller.
- Does it work with "green" fuel blends? Yes, the Siemens UV detector is capable of monitoring flames from renewable liquid energy carriers and hydrogen-enriched fuel blends.
