摘要： An inductive linear displacement sensor arrangement includes a movable coupling device coupled to a movable body, an electrically conductive coupling element, and a stationary circuit carrier. The circuit carrier includes an excitation structure and a receiving structure, which extend along a displacement path of the coupling device. An evaluation and control unit is designed to evaluate a measurement signal induced in the receiving structure and to determine the current position of the coupling device and of the body. The coupling device comprises a slider on which the electrically conductive coupling element is arranged. The slider is mounted for sliding movement in a plane of displacement via the path of displacement of the coupling device on two parallel guide elements, one of which guides the slider of the coupling device along the displacement path, and another of which is a sliding guide which prevents the slider from tilting and/or twisting.

摘要： An inductive type position encoder includes a scale, a detector portion and a signal processor. According to one aspect, field generating elements and sensing elements of the detector portion are provided on opposite sides of the scale such that at least part of the scale is between the field generating elements and the sensing elements (transmissive configuration). According to another aspect, the scale comprises a periodic scale pattern including signal modulating elements that are disposed along a scale direction, which is not parallel to a measuring axis direction of the encoder and is slanted at a scale angle relative to the measuring axis direction, such that there is a corresponding y-direction displacement for a given x-direction displacement of the encoder. These aspects of the disclosure make it possible to design a very compact inductive type position encoder, including one capable of indicating an absolute position along the scale.

The inductive position sensor device includes (i) at least one transmitter coil for generating electromagnetic waves, (ii) at least one receiver coil for detecting the electromagnetic waves which are generated by the transmitter coil and are influenced by the actuator element, and (iii) a computing unit which is designed to actuate the transmitter coil and evaluate the electromagnetic waves detected by the receiver coil in order to determine the position. The coils are arranged on a front face of a common printed circuit board, and the computing unit is arranged on a rear face of the common printed circuit board. The coils are electrically connected to the computing unit by connection lines which extend along the printed circuit board and through the printed circuit board. The connection lines run substantially parallel to one another.
