Sensore di fiamma UV Siemens QRA50M

Siemens QRA50M ultraviolet flame detector — a professional device for reliable monitoring of the presence of a flame in industrial gas, liquid fuel and dual-fuel burners. The sensor is designed for use in automatic combustion control systems and provides a high level of safety during operation of boiler and thermal equipment. The Siemens QRA50M detects ultraviolet radiation from the flame and transmits a signal to the burner control to confirm stable burner operation. When the flame disappears, the sensor ensures instant transmission of a signal for emergency shutdown of fuel supply, which prevents dangerous situations and minimizes the risk of equipment damage. The QRA50M model features high sensitivity, resistance to interference and stable operation under continuous industrial use. The sensor is widely used in boiler plants, industrial furnaces, heat generators, drying complexes and other systems where precise combustion control is required. Advantages of Siemens QRA50M: • Reliable flame monitoring via ultraviolet radiation • Fast response upon flame loss • Suitable for gas, diesel and dual-fuel burners • High sensitivity and stable operation • Compatibility with Siemens burner controls • Resistance to industrial loads and external interference • Durable design and easy maintenance The Siemens QRA50M ultraviolet flame detector is used in industrial automation and thermal power systems where safety, reliability and uninterrupted control of burner equipment operation are especially important. Using original Siemens equipment helps increase the efficiency of the combustion control system and reduce the likelihood of emergency shutdowns.
