    • A measuring arrangement is calibrated for determining rotational positions of a rotary device that has a first part and a second part which can be rotated relative to the first part about a rotational axis. Rotational positions of the first part relative to the second part and/or rotational positions of the second part relative to the first part are detected using a plurality of sensors distributed about the rotational axis. A respective measurement signal corresponding to each detected rotational position is generated such that redundant information on the rotational positions of the first part and the second part relative to each other is provided. The redundant information on the rotational position(s) are analyzed such that effects of a translational movement of the first and the second part relative to each other are corrected, the translational movement running transverse to the extension of the rotational axis.
    • 校准测量装置,用于确定具有第一部分和第二部分的旋转装置的旋转位置,该第一部分和第二部分可相对于第一部分围绕旋转轴线旋转。 使用围绕旋转轴线分布的多个传感器来检测第一部分相对于第二部分的旋转位置和/或第二部分相对于第一部分的旋转位置。 产生对应于每个检测到的旋转位置的相应测量信号,使得提供关于第一部分和第二部分相对于彼此的旋转位置的冗余信息。 分析关于旋转位置的冗余信息,使得第一和第二部分相对于彼此的平移运动的影响被校正,平移运动横向于旋转轴线的延伸。
