Siemens QRA2m (1) flame sensor

Siemens QRA2M (1) flame sensor — a professional ultraviolet flame detector for industrial gas, oil, and dual-fuel burners. The device is designed to detect ultraviolet radiation from the flame and is used in automatic combustion control systems to ensure safe and stable operation of boiler and thermal equipment. Siemens QRA2M (1) provides continuous flame presence monitoring during burner operation. In case of flame loss, the sensor instantly transmits a signal to the burner control for emergency fuel shutdown, helping to prevent accidents, reduce the risk of equipment damage, and enhance industrial safety. The model features high sensitivity to UV radiation, resistance to industrial interference, and reliable operation under intensive use. The sensor is widely used in industrial boilers, heat generators, process furnaces, dryers, and other equipment requiring precise and stable combustion monitoring.
