The blade load acting on the rotor blade is typically determined taking into account the strain acting on the rotor blade detected by the strain sensor. The rotor angle has hitherto been utilized to align the strain sensor. However, the detection of the rotor angle is typically unreliable or imprecise, and therefore, the simple and precise alignment of the strain sensor has hitherto been not sufficiently precise solved.
