Abstract
A sensor device for measuring aerodynamic loads of a rotor blade for a wind power installation. The sensor device includes a reflector arranged in a cavity of the rotor blade which signals a signal evaluation device arranged at a distance from the reflector. The signal evaluation device detects and quantifies physical changes of the rotor blade from the reflected signal. A cleaning device for the reflector is arranged on the reflector for activation by a centrifugal force generated during the rotation of the rotor to clean the reflector.
