Siemens Combustion QRA73.A17 Detector
The Siemens QRA73.A17 is a precision-engineered UV flame detector built for continuous supervision in high-demand industrial and commercial combustion environments. Designed for seamless integration with LMV5 and LME7 burner management systems, this detector operates on a 110V/120V AC power supply and provides reliable monitoring for gas flames, blue-burning oil flames, and ignition sparks. Featuring an integrated self-checking mechanism, the unit periodically verifies sensor functionality, ensuring failsafe operation without the need for manual cycling or intermissions. With a 125mm detector tube length and a rugged IP65-rated housing, the QRA73.A17 is built to withstand the thermal and mechanical stresses of modern boiler rooms. Its side-viewing design and normal sensitivity photodiode allow for flexible mounting while maintaining rapid response times to flame failure, making it a critical component for technicians maintaining high-performance flame safeguard systems.
Key Benefits- Sustained Safety Monitoring: Integrated self-check electronics allow for continuous operation by identifying sensor fatigue or failure automatically.
- Broad Compatibility: Native support for Siemens LMV5 and LME7 burner controls ensures "plug-and-play" integration for high-end combustion systems.
- Industrial-Grade Durability: The metalized plastic housing and IP65 protection class provide resistance against environmental contaminants and static interference.
- Versatile Mounting: Standard 125mm tube length and bayonet fitting allow for easy installation into existing viewing tubes or via AGG16.C adapters.
- Proven Performance: Designed to meet stringent international standards for continuous supervision of oil and gas fuels.
What is the primary difference between the QRA73.A17 and QRA75 models?
The QRA73.A17 features a 125mm detector tube, whereas QRA75 models typically utilize a shorter 69mm tube. Ensure your mounting depth and viewing angle require the longer 125mm profile before installation.
Does this detector require a specific connection cable?
Yes, for new installations, you will typically require the AGM23U or compatible connecting cable to interface the 5-pin detector with the burner management system.
Can this unit be used for intermittent burner operation?
While optimized for continuous supervision, it is fully compatible with intermittent systems; however, its self-checking capabilities are specifically designed to meet the code requirements for burners running longer than 24 hours without a cycle.
