Siemens QRA10M.C UV flame sensor

Siemens QRA10M.C ultraviolet flame detector — a highly sensitive device for monitoring flame presence in industrial gas, oil and dual-fuel burners. The detector is designed for use in automatic combustion control systems and provides reliable monitoring of combustion processes in boiler, thermal and industrial equipment. Siemens QRA10M.C detects ultraviolet radiation from the flame and transmits a signal to the burner control unit to confirm stable burner operation. Upon flame loss, the device instantly initiates emergency fuel shut-off, increasing equipment operational safety and reducing the risk of emergency situations. The QRA10M.C model features high sensitivity, immunity to external interference and reliable operation under intensive use. The detector is compatible with Siemens automation and is widely used in industrial boilers, furnaces, heat generators and process plants where accurate and stable flame monitoring is required. Advantages of Siemens QRA10M.C: • Accurate flame monitoring via ultraviolet radiation • Fast response to flame loss • Suitable for gas, oil and dual-fuel burners • High reliability and durability • Resistance to industrial loads and interference • Compatibility with Siemens burner controls • Easy installation and maintenance The Siemens QRA10M.C ultraviolet flame detector is used in industrial automation systems, boiler plants and thermal power equipment where safety, stable operation and uninterrupted combustion monitoring are especially important.
