被测物相对于传感器的位置和/或位置变化的测定方法及测定用的传感器装置
摘要：
本发明涉及一种被测物相对于传感器(2)的位置和/或位置变化的测定方法，其中所述传感器(2)优选具有施加以交流电的传感线圈(7)，其特征在于：软磁金属薄片(4)中与被测物(1)关联的磁铁(5)使金属薄片(4)的磁导率产生变化，金属薄片(4)的磁导率在磁场的作用下随磁场的场强变化而变化并安排在传感器(2)的作用范围内，而金属薄片(4)的磁导率变化由被测物对传感器(2)的反应来确定并可用于测定被测物(1)相对于传感器(2)的位置和/或位置变化。从而设计出一种传感器装置。
摘要（英）：

A method for determining the position and/or change of position of a measured object relative to a sensor (2), where the sensor (2) preferably has a sensor coil (7) to which an alternating current is applied, is characterized in that a magnet (5) associated with the measured object (1), in a soft magnetic foil (4), whose permeability changes under the influence of a magnetic field on the basis ofthe magnetic field's field strength and which is arranged in the area of influence of the sensor (2), brings about a change in the permeability of the foil (4) and in that the change in the permeability of the foil (4) is determined from the latter's reaction to the sensor (2), and this is used to determine the position and/or change of position of the measured object (1) relative to the sensor (2). A sensor arrangement is designed accordingly.
