位置测量装置及用于确定测量对象的位置的方法
摘要：
在位置测量装置(5)和用以确定待测对象(3)的位置的方法中，提供至少一个电容式位置测量传感器(7)，以提供关于待测对象(3)的位置测量信号(PM)，并且提供至少一个电容式基准测量传感器(14)，以提供基准测量信号(RM)。测量传感器(7、14)连接到计算单元(8)，该计算单元被设计为从位置测量信号(PM)和基准测量信号(RM)计算位置信号(P)，以便确定位置。因为干扰信号(S)形式的干扰影响基本上相同程度地包含于位置测量信号(PM)和基准测量信号(RM)中，可以在计算中确定干扰信号(S)并消除干扰信号(S)。
摘要（英）：

In a position measuring device (5) and a method for determining positions of a measurement object (3), at least one capacitive position measuring sensor (7) is provided for the purpose of providing a position measurement signal (PM) pertaining to the measurement object (3) and at least one capacitive reference measuring sensor (14) is provided for the purpose of providing a reference measurement signal (RM). The measuring sensors (7, 14) are connected to a computing unit (8) which is designed to calculate a position signal (P) from the position measurement signal (PM) and the reference measurement signal (RM) for the purpose of determining the positions. Since interfering influences in the form of an interfering signal (S) are contained to substantially equal extents in the position measurement signal (PM) and the reference measurement signal (RM), the interfering signal (S) can be determined and eliminated in the calculation.
