Siemens QRB1B-A042B20B – czujnik płomienia

Siemens QRB1B-A042B20B flame detector is a reliable photosensor for monitoring the presence of flame in 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 the combustion process in domestic, commercial and industrial heating systems. Siemens QRB1B-A042B20B detects the light emission of the flame and transmits a signal to the burner control. When the flame disappears, the sensor instantly initiates an emergency shutdown of the fuel supply, which helps prevent emergency situations, increase equipment safety and protect the system from damage. The model features high sensitivity, stable operation and durability even under intensive use. The sensor is widely used in diesel and fuel oil burners of boilers, heat generators and other heating equipment where reliable flame monitoring and uninterrupted operation of automation are required.
