BFR11 Series Compact UV Flame Detector

The BFR11 series is a robust compact UV-flame detector/sensor specifically designed for use in industrial combustion systems. This UV-flame detector can be connected directly to a tuned ionization or LDR input of the burner control. The flame intensity can be easily detected via an LED as an optical display.

In accordance with EN298:2012-11, the BFR11 flame sensor is intended for burner control systems that check for a presence of a flame signal after a control shutdown. The UV tube ensures that the background radiation, for example, from glowing brick linings or mixing equipment parts, is not detected. The internal boost of the UV tube voltage immediately after applying the supply voltage ensures the safety requirement according to EN298:2012-11 for checking the UV tube for burn through for intermittent burner operation.
