Abstract
Position measurement system of the relative position between two objects. The system comprises a first and a second inductive system. The first inductive system comprises a transmitting coil and a first detector, with the attribute that the pattern of conductors that form the coil extends along a longitudinal axis. A second inductive system comprises a second transmitting coil and a second detector, with the attribute that the coil extends essentially in the longitudinal direction. The second trasmitter coil can be realised as a Meander pattern of conductive material, with return path in its center-line. Using the detectors, it is possible to accurately determine the linear and/or angular position(s) of two bodies relative to each other.
