    Abstract: Double-emitting and multiple-receiving capacitive measuring device: it comprises a scale equipped with an array of electrodes and a transducer, which moves parallel to and opposite the scale and is equipped with two emitting electrodes and an array of receiving electrodes distributed into N groups. The capacitive coupling between the different electrodes allows the position of the transducer to be determined. A generator emits two emission signals (E0, E1) in phase opposition on the two emitting electrodes of the transducer. The frequency of generated emission signals (E0, E1) depends upon the speed of displacement of the transducer. Processing means determine a dimension with the aid of N signals (R0, R7) received on the receiving electrodes. The more significant bits of the result are provided by a primary counting system using a first algorithm. The less significant bits are provided by a secondary precision system using a second algorithm.

    Abstract: A capacitive measuring device has a scale and a transducer, both provided with an array of electrodes. The position of the transducer with respect to the scale is determined in a processing circuit by evaluating the capacitances formed between the two arrays. These capacitances vary periodically as a function of the relative position of the transducer. The scale electrodes are spaced by a pitch (.lambda.). In order to increase the resolution, the transducer electrodes occupy possible initial positions spaced by an elementary interval (P) which is a submultiple of the pitch (.lambda.). The transducer electrodes are thus divided into N groups according to the initial position which they occupy. In order to compensate for manufacturing imprecisions of periodic type, the succession of transducer electrodes is highly non-periodic. To this end, the set intervals (I.sub.j) occupied by the sets of successive electrodes interpenetrate, and the number of unoccupied possible initial position between the bundles of electrodes is variable. A set of electrodes is a set composed of one electrode of each group.
