Inductive position detector and method for determining displacement

本发明涉及一种电感式位置检测器(1)以及用于确定位移的方法，该电感式位置检测器包括具有一纵向轴的第一部件(9)和在纵向轴的方向延伸、并且在垂直于纵向轴的方向具有周期性变化尺寸的磁性元件，和可以沿着纵向轴相对于第一部件移动的第二部件(10)，并包括用于感应该元件中的磁场的装置。该位置检测器分析磁场的特性变化以确定第一部件相对于第二部件的位置。 The invention relates to an inductive position detector ( 1 ) comprising a first member ( 9 ) having a longitudinal axis and an element of magnetic material extending in the direction of the longitudinal axis and having a periodically varying dimension in a direction perpendicular to the longitudinal axis, and a second member ( 10 ) movable relatively to the first member along the longitudinal axis and comprising means to induce a magnetic field in the element. The position detector analyses characteristic variations in the magnetic field to determine the position of the first member relative to the second member.
