摘要：
This invention concerns a measuring device for contactless capture of the angle of rotation which consists of a rotor (22) and a stator (10). The stator (10) consists of two segments (13, 14) separated by a gap and an external housing part (11) in the form of a pot. Both segments (13, 14) and the pot-shaped housing part (11) consist of magnetically conducting material. One segment (14) is set directly upon the floor (15) of the housing part (11), so that a magnetically conductive connection arises. A layer (18) of material which is not magnetically conductive is located between the other segment (13) and the floor (15), so that no magnetic flux is possible here. The rotor is a permanent magnet (22) which is arranged so that it remains movable in an air gap between the two segments (13, 14) and the housing part (11). The direction of polarisation of this magnet (22) is radial, i.e. oriented towards or away from the segments (13, 14). The measuring element (20) is located in the slot (12) between the two segments (13, 14). Based on this embodiment it is possible to divide the magnetic flow so that a displacement of the linear measuring area is possible and thus no change in sign appears within the linear measuring area.
摘要（中）：
对于接触检测的旋转角的测量装置包括一转子（22）和定子（10）的。 所述定子（10）由两个通过一个切口片段（13，14）和外锅形的壳体部分（11）分离。 两个节段（13，14）和罐形的壳体部分（11）由导磁材料制成。 一个段（14）是直接在壳体部件（11）的底板（15）安装成使得有导磁连接。 其他段（13）和底部（15）之间有非导磁材料制成的层（18），这样就没有磁通是可能的。 成所述两个部段之间的空气间隙（21）被用作一个转子（13，14）和所述外壳部件（11）可移动地布置永久磁铁（22），其偏振方向沿径向，即 上段（13，14）朝向或与其相对，被对准。 在所述两个部段（13,14）之间的槽（12）的测量元件（20）。 由于这种结构配置的，能够分裂的磁通，所述线性测量范围的位移是可能的，因此，没有符号变化的线性测量范围内发生。
