Siemens QRA10.C UV flame sensor

Siemens QRA10.C ultraviolet flame detector — a reliable flame monitoring device for industrial gas, oil and dual-fuel burners. The detector is designed to detect ultraviolet radiation from the flame and is used in automatic combustion control systems to ensure safe operation of boiler and thermal equipment. Siemens QRA10.C is used in industrial boilers, furnaces, heat generators and process plants where accurate and stable flame presence monitoring is required. The detector responds quickly to flame loss and sends a signal to the burner control unit for emergency fuel shut-off, helping to prevent hazardous situations and improve equipment operational safety. The Siemens ultraviolet detector features high sensitivity, immunity to interference and reliable operation under intensive use. The compact design and compatibility with Siemens automation make the QRA10.C model a convenient solution for upgrading and servicing burner systems. Advantages of Siemens QRA10.C: • Accurate flame presence monitoring via UV radiation • Fast response to flame loss • Suitable for gas, oil and dual-fuel burners • High reliability and stable operation • Resistance to industrial loads and interference • Compatibility with Siemens burner controls • Easy installation and maintenance The Siemens QRA10.C flame detector is widely used in industrial automation and thermal power systems where safety, control accuracy and uninterrupted equipment operation are especially important. Using an original Siemens UV detector helps reduce the risk of emergency shutdowns and improve the efficiency of the burner system. Siemens QRA10.C — the optimal solution for replacing sh
