Abstract:
1. A position sensor comprising at least two coils, the first coil being supplied with a specific frequency so that it emits a constant electromagnetic field and this field being received or detected by means of a second coil, wherein the axis of the second coil is angled relative to the axis of the first coil, and the first coil is positioned on a first object and the second coil is positioned on a second object, wherein the relative position between said first and second objects is to be measured; the position sensor further comprising a third coil that emits a constant electromagnetic field and a fourth coil and a fifth coil that receive or detect the constant electromagnetic field of the third coil, the first coil being mechanically connected to the third coil, and the axis of the third coil lying in the same direction as that of the first coil, the first coil and the third coil lying next to each other, the second coil lying next to the fourth coil and the fifth coil, and the fourth coil and the fifth coil are arranged very close next to each other with a common axis and that their common axis runs in the same direction, wherein said common axis is orthogonal to the axis of the second coil.
