Siemens Combustion QRI2B2.B180B1 Flame Detector
The Siemens QRI2B2.B180B1 is a high-sensitivity infrared flame detector designed for the supervision of gas, oil, or coal flames in large-scale industrial or commercial burner systems. Engineered for lateral (side viewing) illumination, it features a 90-degree light entry path, making it the standard choice for specific burner mounting configurations where frontal line-of-sight is obstructed. This self-checking sensor operates within a 1 to 3 µm spectral range, utilizing an integrated signal amplifier to deliver a DC 0…5 V flame signal to high-level burner controls like the Siemens LMV5 or LME7 series. Its electronic self-supervision ensures reliability in both continuous and intermittent operations. Built with a dust-tight lens and an impact-proof black plastic housing, the unit is rated for IP54 protection. The factory-integrated 180cm cable features stripped ends and ferrules, arriving ready for termination. Technicians should ensure the detector is positioned behind a baffle plate to prevent extraneous light from simulating a flame signal.
Key Benefits
- Broad Fuel Compatibility: Reliably detects infrared radiation from gas, oil, and coal flames, providing a versatile solution for multi-fuel burner setups.
- Optimized for Side-Viewing: The 90-degree lateral light entry allows for precise flame monitoring in complex burner geometries without specialized mirrors.
- Integrated Signal Processing: Features a built-in amplifier that converts IR light into a stable voltage signal, reducing the risk of interference and simplifying control logic.
- Robust Industrial Design: The IP54-rated housing and dust-tight lens maintain HVAC burner sensor performance in high-temp (up to 60°C) and high-vibration environments.
- Ready for Installation: Ships with a 180cm (70 inch) thermal-resistant cable, plus the necessary mounting flange and clamp for immediate field integration.
Common Questions
Can I use the QRI2B2.B180B1 for continuous burner operation?
Yes, because of its electronic self-supervision, this Siemens combustion control sensor is fully rated for both continuous and intermittent operation cycles when paired with compatible burner controls.
How do I prevent false flame signals from hot refractory cooling?
To prevent the detection of infrared "heat streaks" from glowing combustion chamber linings, always position the sensor behind a baffle plate and ensure it is aimed specifically at the flame sensor detection zone.
What is the maximum cable run length allowed for this detector?
While it comes with a 180cm lead, the cable can typically be extended up to a maximum of 100 meters, provided you use high-quality shielded cabling to prevent signal degradation on the DC 14V supply lines.
