ОПИСАНИЕ ПРОДУКТА
SIEMENS QRA2 - UV Flame Detector
The SIEMENS QRA2 is a compact ultraviolet flame detector designed for continuous flame supervision in industrial combustion processes. It generates a flame presence signal for integration with compatible burner control units, supporting safe operational sequences for gas and oil burners in furnaces, boilers, and heating plants. This device employs UV radiation detection technology to monitor combustion, enabling rapid detection of flame failure conditions.
