Flame detection UV radiation sensing Combustion control Industrial burners Safety monitoring

Product description

The Siemens QRA2M is a flame detector used in combustion control systems. It typically works by sensing the ultraviolet (UV) radiation emitted by a flame, providing a signal to the burner control unit. This allows for monitoring and control of the combustion process, ensuring safe and efficient operation.

This flame detector is commonly applied in industrial burners, boilers, furnaces, and other combustion equipment where reliable flame detection is critical. Its purpose is to ensure that a flame is present when it should be and to shut down the fuel supply if the flame is extinguished, preventing hazardous situations.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, offers the Siemens QRA2M. We provide essential components for your industrial control and safety systems.
