Abstract
In order to provide a position measuring system, comprising a transmitter, a sensor with an inductive element to which the transmitter is coupled electromagnetically and an evaluating unit, wherein the sensor and the transmitter are adapted to be positioned relative to one another, whereby said position measuring system will be of simple construction and can thus be manufactured economically while being employable universally, provision is made for the inductive element to be coupled to an oscillator which is affected by the Q factor and/or the effective inductance of the inductive element, for the Q factor and/or the effective inductance of the inductive element to be determined by the size of an effective sensor region to which the transmitter is coupled, and/or by the size of an effective transmitter region which is coupled to an effective sensor region, and for the sensor and/or the transmitter to be formed in such a manner that the size of the effective sensor region to which the transmitter is coupled, and/or the size of the effective transmitter region which is coupled to the effective sensor region is dependent upon the relative position between the transmitter and the sens…
