Siemens QRA2(1) Czujnik płomienia UV

Siemens QRA2(1) ultraviolet flame detector — professional flame monitoring sensor for industrial gas, liquid fuel and dual-fuel burners. The device is designed to detect ultraviolet radiation from the flame and is used in automatic combustion control systems to ensure safe and stable operation of boiler equipment. The Siemens QRA2(1) is used together with Siemens burner controls and provides continuous monitoring of the presence of a flame during burner operation. When the flame disappears, the sensor instantly transmits a signal to the automation system for emergency shutdown of fuel supply, preventing dangerous situations and increasing the level of industrial safety. The model features high sensitivity to UV radiation, immunity to interference and stable operation under intensive use. The sensor is widely used in industrial boilers, furnaces, heat generators, drying plants and other thermal equipment where reliable combustion control is required. Advantages of Siemens QRA2(1): • Accurate flame monitoring via ultraviolet radiation • Fast response upon flame loss • Suitable for gas, diesel and dual-fuel burners • Compatibility with Siemens burner controls • High reliability and long service life • Resistance to industrial loads and interference • Easy installation and maintenance The Siemens QRA2(1) ultraviolet flame detector helps ensure safe operation of burner equipment, reduce the risk of emergency shutdowns and increase the efficiency of the combustion control system. Using original Siemens equipment guarantees stable operation and compliance with modern industrial automation requirements.
