First sensor device for measuring a torsion, sensor device for measuring a flexion and a torsion and arrangement for measuring a torsion or torsion with flexion

摘要

The invention relates to a first sensor device for measuring a torsion, in which a first optical waveguide with sensitive zones in the form of a loop is arranged in one plane, wherein a torsion suspension by crossing points of the crossing first loops of the first light guide, the sensitive zones in a defined by the torsion axis of the half of the first loops to the left and right of a respective apex point of the respective first loop are arranged, and wherein the sensitive zones in this case are arranged in such a way that it comprises a due to the torsion occurring bending of the first light guide in a respective region of the sensitive zones displaying. It is also part of the invention, a sensor device, which has a first sensor device for measuring a torsion and a second sensor device for measuring a flexion, wherein the second sensor device also in the form of a loop in a plane is arranged, at respective vertices of said second loops of the second optical fiber sensitive zones are arranged in such a way that on the basis of the flexion occurring bending of the second light guide in the respective region of the sensitive zone displays. Finally, an arrangement for measuring a torsion or a torsion and flexion part of the invention, wherein this arrangement of at least two first sensor devices or at least two sensor devices, which are arranged one behind the, ..
