مستشعر اللهب Siemens QRB1B-A148B70B

Siemens QRB1B-A148B70B flame sensor is a reliable photodetector for monitoring the presence of flame in liquid fuel burners, designed for safe and stable operation of boiler and thermal equipment. The device is used in automatic combustion control systems and provides precise monitoring of the combustion process in domestic, commercial, and industrial heating systems. Siemens QRB1B-A148B70B detects the light emission of the flame and transmits a signal to the burner control. If the flame goes out, the sensor immediately 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, stable operation, and resistance to long-term operational loads. The sensor is widely used in diesel and fuel oil burners of boilers, heat generators, and other heating equipment where reliable flame presence monitoring and uninterrupted operation of automation are required.
