Sensore di fiamma Siemens QRB1A-B110B70A

Siemens QRB1A-B110B70A flame sensor is a highly sensitive photodetector for monitoring flame presence in liquid fuel burners. The device is designed for use in automatic combustion control systems and ensures safe, stable, and efficient operation of boiler and heat engineering equipment. Siemens QRB1A-B110B70A monitors the combustion process by detecting the light emission of the flame and transmitting a signal to the burner control. If the flame goes out, the sensor instantly initiates an emergency fuel shut-off, helping to prevent accidents, improve operational safety, and protect the system from damage. The model features high sensitivity, reliable operation, and resistance to long-term operational loads. The sensor is widely used in diesel and heavy oil burners of heating boilers, heat generators, and other equipment requiring precise flame monitoring and uninterrupted automatic control.
