Siemens Combustion QRI2A2.B180B Flame Detector
The Siemens Combustion QRI2A2.B180B Flame Detector is a high-precision infrared (IR) sensor specifically engineered for the supervision of gas, oil, and other hydrocarbon flames that emit infrared light. Designed for industrial and commercial burner applications, this infrared flame detector features advanced electronic self-supervision, making it ideal for systems in continuous or intermittent operation. The frontal illumination (forward-viewing) design is optimized for monitoring radiation behind the burner's baffle plate where UV sensors may fail to provide adequate signal strength. With a spectral sensitivity peak at approximately 2 ?m, it effectively ignores short-wave radiation from ignition sparks to prevent false flame indications. This Siemens QRI series detector integrates a flame signal amplifier and is fully compatible with Siemens LMV5 and LME7 burner management systems. The factory-connected 180 cm 3-core cable with stripped ends and ferrules ensures a stable 0 to 5V DC signal output for precise monitoring and safety compliance in high-capacity boiler environments.
- Continuous Operation Reliability: Features electronic self-supervision for safe use in non-stop burner applications without internal shutters.
- Precise IR Detection: Optimized spectral sensitivity for gas and oil flames, filtering out interference from ignition sources.
- Flexible Integration: Designed for seamless interface with Siemens burner control units via a standard 14V DC power supply.
- Robust Construction: Housed in impact-proof black plastic with a dust-tight lens (IP54 rated) for harsh mechanical room conditions.
Common Questions
What is the maximum cable length allowed for the QRI2A2.B180B?
While the unit comes with a standard 180 cm lead, the cable can be extended up to a maximum of 100 meters if specific installation guidelines regarding shielding and signal interference are followed.
Does the QRI2A2.B180B detect the ignition spark?
No. Due to its specific short-wave spectrum sensitivity, this detector is designed to ignore the ignition spark and focus solely on the infrared radiation emitted by the flame.
Is this detector suitable for lateral illumination?
This specific model (QRI2A2) is designed for frontal illumination. For lateral or 90-degree viewing requirements, the QRI2B series should be utilized instead.
