1. Product Title

Siemens BPZ:QRA50M‑ UV Flame Detector for Burner Systems

2. Product Overview

BPZ:QRA50M (QRA50M) is a UV‑sensitive flame detector for continuous‑operation gas and oil burners. It captures ultraviolet radiation emitted by combustion flames, converting optical signals into electrical flame‑status signals for burner safety controllers. Designed for long‑run continuous burner operation, it monitors flame presence and triggers safety interlock actions upon flame loss to avoid unburned‑fuel accumulation risk. Mechanical mounting clamp and dedicated connecting cables facilitate field installation. Widely used in boiler, thermal‑oil‑heater and industrial furnace combustion‑safety systems, it serves as critical spare for flame‑detection‑signal‑loss faultssiemens-la….
