Capteur de flamme Siemens QRA2m

Flame sensor Siemens QRA2M — a professional ultraviolet flame detector for industrial gas, oil, and dual-fuel burners. The device is designed to detect UV radiation from the flame and is used in automatic combustion control systems to ensure safe and stable operation of boiler and heat engineering equipment. Siemens QRA2M provides continuous monitoring of flame presence during burner operation. If the flame goes out, the sensor instantly sends a signal to the burner control for emergency fuel shut-off, helping to prevent accidents, reduce the risk of equipment damage, and increase industrial safety. Thanks to high sensitivity and robust design, Siemens QRA2M operates stably under intensive use and is resistant to industrial interference. The sensor is widely used in boiler plants, industrial furnaces, heat generators, drying chambers, and other equipment requiring precise combustion control. Advantages of Siemens QRA2M: • Accurate flame detection via ultraviolet radiation • Fast response to flame loss • Suitable for gas, oil, and dual-fuel burners • Compatibility with Siemens burner controls • High reliability and stability • Resistance to industrial loads and electromagnetic interference • Easy installation and maintenance. The ultraviolet flame sensor Siemens QRA2M is in demand in industrial automation and thermal power engineering, where safety, uninterrupted operation, and reliable flame monitoring are especially important. Using original Siemens equipment helps minimize the risk of emergency shutdowns and improve burner operation efficiency.
