ОПИСАНИЕ ПРОДУКТА
SIEMENS QRA2M - Ultraviolet Flame Detector
The SIEMENS QRA2M is an ultraviolet (UV) flame detector engineered for reliable flame supervision in industrial burner systems. This sensor monitors the UV radiation emitted by gas and oil flames, providing a critical safety signal to compatible SIEMENS burner control units. It is integral for ensuring safe ignition and continuous operation in heating plants, boilers, furnaces, and process heating applications.
