摘要： A device for measuring an angle and/or the torque acting on a rotatable body is proposed according to the invention, whereby the rotational angle is detected by means of magnetic or optical sensors. In particular, in a preferred exemplary embodiment, two devices (7, 8) are proposed, each of which comprises two optically readable code tracks. The two code tracks (1a, 1b or 2a, 2b) on one device (7 or 8) are similar in design and are offset in relation to each other, so that associated sensors (4) output a digital signal. The rotational angle is calculated based on the lag between the two digital signals. In a further embodiment it is provided that a torsion element (5) having a known torsional stiffness is situated between the two devices (7, 8). Torque transferred by the rotatable body (3) can also be calculated therefore from the angular difference of the two devices 7, 8. The device is used preferably in the steering axle of a motor vehicle.
