Abstract

A device is for the optoelectronic measurement of torque with a first component (2), and a second component (3), it being possible for the first component (2) to be connected to a drive element and the second component (3) to be connected to a drive element, or vice versa. A first encoding element that is arranged on the first component (2). A second encoding element is arranged on the second component (3). A first light barrier (6) detects the rotational movement of the first encoding element. A second light barrier (7) detects the rotational movement of the second encoding element. An electronic evaluation unit (8) detects and evaluates signals originating from the first light barrier (6) and second light barrier (7), with at least one elastic element that is deformable according to a torque acting upon it being provided between the first (2) and the second component (3). When the torque changes, a change in the angle-of-rotation position of the components (2, 3) in relation to one another can be identified and the torque calculated on that basis.
