Siemens Combustion QRA75.A17 Detector
The Siemens Combustion QRA75.A17 is a high-precision, self-checking UV detector engineered specifically for continuous-duty industrial burner applications. Designed for the supervision of gas and oil flames, this ultraviolet flame detector utilizes a high-sensitivity UV cell to monitor combustion and ignition spark proving with professional-grade reliability. Operating at AC 120 V, the QRA75.A17 features a 69mm detector tube and a built-in stepper motor that drives a mechanical shutter, facilitating periodic self-testing of the UV cell without interrupting burner operation.
This self-checking flame scanner is essential for high-demand systems where safety-critical flame supervision is mandatory. Its IP65 rated housing is metalized to mitigate static charging from fan airflow, ensuring stable signal transmission in harsh mechanical environments. For technicians and contractors, the QRA75.A17 serves as a direct replacement component for Siemens burner control series including the LMV5 and LME7, providing the flame supervision accuracy required to prevent hazardous fuel buildup during high-cycle operations.
Key Benefits- Continuous Flame Supervision: Integrated mechanical shutter allows for constant self-checking, making it suitable for burners in 24/7 operation.
- Enhanced Signal Stability: The metalized plastic housing prevents interference from static electricity and high-velocity fan air.
- Seamless Integration: Standardized mounting coupling allows for direct installation on burners or viewing tubes.
- Precise Detection: Normal sensitivity UV photodiode accurately identifies gas flames and blue/yellow burning oil flames while ignoring glowing firebrick.
- What burner controls is the QRA75.A17 compatible with? It is designed for use with the Siemens LMV5 and LME7 burner control systems.
- Does this detector require a specific cable? Yes, for US installations, the AGM23U connecting cable is typically required along with the AGG16.U adapter.
- Can it monitor ignition sparks? Yes, it is rated for both flame supervision and ignition spark proving.
