Sensor de llama Siemens QRB4B-B036A25

Siemens QRB4B-B036A25 flame sensor is a highly sensitive photodetector for monitoring flame presence in oil-fired 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 QRB4B-B036A25 detects the light emission of the flame and transmits a signal to the burner control. When the flame goes out, the sensor instantly initiates an emergency shutdown of fuel supply, helping to prevent accidents, increase 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 where precise combustion monitoring and uninterrupted automatic operation are required.
