Siemens QRB1B-A035B40A – czujnik płomienia

Siemens QRB1B-A035B40A flame sensor is a reliable photoelectric flame detector for liquid fuel burners, designed for safe and stable operation of boiler and heat engineering equipment. The device is used in automatic combustion control systems and provides accurate monitoring of flame presence during burner operation. Siemens QRB1B-A035B40A detects the light emission of the flame and transmits 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, stable operation, and reliability over long-term use. The sensor is widely used in diesel and heavy oil burners of heating boilers, heat generators, and other heat engineering equipment requiring reliable combustion monitoring and uninterrupted automatic control.
