Abstract
A measurement arrangement for measuring a deflection of a wind turbine rotor blade is provided. The measurement arrangement includes a magnetostrictive sensor, which includes a first sensor part and a second sensor part, a first support structure, which is adapted to be mounted to a first portion of the rotor, wherein the first sensor part is mounted to the first support structure, and a second support structure, which may be mounted to a second portion of the rotor, wherein the second sensor part is mounted to the second support structure and wherein either or both the first portion and the second portion is a portion of the blade. The magnetostrictive sensor measures the relative spatial position between the first sensor part and the second sensor part. A method for measuring a blade deflection and a wind turbine rotor which includes the described blade deflection measurement arrangement are also provided.
