Claim Text:
1. A measuring system comprising: a magnetic field sensor array that has a first magnetic field sensor integrated into a semiconductor chip for measuring a first component of a magnetic field vector in a first spatial direction, a second magnetic field sensor integrated into a semiconductor chip for measuring a second component of the magnetic field vector in a second spatial direction, and a third magnetic field sensor integrated into a semiconductor chip for measuring a third component of the magnetic field vector in a third spatial direction, wherein the first spatial direction, the second spatial direction and the third spatial direction are orthogonal to one another; an encoder adapted to change the magnetic field vector in the first spatial direction and in the second spatial direction and in the third spatial direction as a function of a rotatory and/or translational movement, wherein the change of the magnetic field vector in all three spatial directions, caused by the movement of the encoder, traces a closed and non-intersecting path through space; and an evaluation circuit connected to which the first magnetic field sensor, the second magnetic field sensor and the third magnetic field sensor, the evaluation circuit determining a three-dimensional position of the encoder based on a first measurement signal of the first magnetic field sensor and a second measurement signal of the second magnetic field sensor and a third measurement signal of the third magnetic field sensor.
