Product Details
Energy combustion, Ahmedabad Importer and suppliers of Siemens Brand Flame sensor. Siemens offers several types of infrared (IR) flame sensors, each designed for specific burner controls and fuel types. While they all use IR technology, they differ significantly in their application—ranging from basic oil burner monitoring to high-end industrial burner management. 1. Siemens QRI Series (High-End / Industrial) The QRI series is designed for high-capacity burners and is typically used with the LMV5 series burner controls. It is suitable for continuous operation (24+ hours) and can supervise gas, oil, or coal flames. Models: QRI2A: Frontal illumination (looks straight ahead). QRI2B: Lateral illumination (90° side-view). Key Specs: DC 0–5 V signal output, electronic self-supervision, and a spectral sensitivity peak at approx. 2 $\mu$m. Best For: Industrial burners where reliability and continuous operation are critical. 2. Siemens QRB Series (Standard / Commercial) The QRB series uses photo-resistive sensors. These are primarily used for intermittent operation (burners that shut down at least once every 24 hours) and are designed to monitor yellow-burning oil flames. Models: QRB1, QRB3, and QRB4. Compatibility: Works with LAL, LME, LMO, and LOA burner controls. Detection: Monitors the visible light spectrum of the flame. Best For: Standard residential or commercial oil burners. 3. Siemens FDF Series (Fire Safety / Facility) Unlike the QRI and QRB which sit inside a burner, the FDF series (like the FDF241-9) are wide-area flame detectors used for facility fire protection. Technology: Uses Triple-IR (IR3) technology (three pyroelectric sensors) to distinguish between real fires and sources of interference like sunlight. Application: Monitoring large industrial rooms, hangars, or chemical storage for open flames.
