Abstract
A damper assembly includes a damper frame, at least one damper blade, an actuator and a sensor module coupled to a first rotatable damper element. The one or more damper blades are movably attached to the damper frame to at least partially regulate air flow proximate the damper frame. The actuator is configured to control a position of the damper blade. The rotatable damper element is operably coupled between the actuator and the damper blade. The sensor module includes a sensor device operable to determine an air-flow induced force on the rotatable damper element.
