Functional description

The damper blade works as a control element and as a differential pressure sensor. Through the differential pressure duct in the shaft, the detected differential pressure reaches the transducer (static or dynamic), and is converted into an electrical signal and compared with the setpoint value. In case of a control deviation, the integrated actuator changes the position of the damper blade. Thereby, the volume flow rate is kept constant in close tolerances over the entire differential pressure range.
