Siemens Combustion QRA2M(1) Detector

Siemens Combustion QRA2M(1) Detector

The Siemens QRA2M(1) is a high-sensitivity ultraviolet flame detector engineered for supervising gas and oil flames in industrial and commercial burner systems. Utilizing an intermittent operating mode, this UV flame detector monitors radiation intensity during each half cycle to provide accurate signal current to Siemens burner controls for safety-critical flame supervision and ignition spark proving. The QRA2M(1) features a robust, metalized plastic housing to prevent static charging from fan air flow and includes a green terminal cover for quick technical identification. This model comes equipped with a mounting flange and clamp, facilitating direct integration onto the burner. With an IP40 rating and a service life approximately averaging 10,000 hours at 50°C, it ensures reliable combustion safety and prevents nuisance shutdowns in complex HVACR environments. Designed for engineers and OEMs, this detector is a standard component for ensuring precise flame monitoring and adherence to strict safety protocols in process heating applications.

Key Benefits for Technicians
  • High Sensitivity Detection: Optimized for gas and oil flames, including blue flames and ignition spark sensing.
  • Integrated Mounting Solution: Ships with the required mounting flange and clamp for streamlined field installation.
  • Static Protection: Metalized housing protects the UV cell from electrostatic interference caused by high-velocity combustion air.
  • System Compatibility: Seamlessly interfaces with Siemens combustion controls to maintain intermittent burner operation safety.
Common Questions

What is the difference between the QRA2 and the QRA2M(1)?
The QRA2M(1) is the high-sensitivity variant of the standard QRA2 series. It is specifically designed for applications where flame signal strength is marginal or requires a more responsive ultraviolet sensor, and it includes the terminal cover and flange set.

Can this detector be used for continuous operation?
No, the QRA2M(1) is rated for intermittent operation. For burners requiring continuous operation (24+ hours), a self-checking UV detector from the QRA5 or QRA7 series should be used to ensure ongoing safety cell checks.

How does the mounting flange assist in installation?
The included flange and clamp allow the technician to secure the detector directly to the burner housing or a viewing tube, ensuring the sensor remains aligned with the flame's primary radiation zone for a consistent signal.
