Abstract

The invention relates to a position sensor including at least two sensor units which measure in a contactless manner a position x of an element which is movably arranged relative to the sensor units. Using limited circuitry, the invention precludes sources of errors during the processing of the sensor signals in that from the sensor signals there is formed a measuring signal from the phase position of which relative to the clock signal there can be determined the position x. The position x may be, for example an angle or a length position.
