ABSTRACT:
The electro-optic measurement tapping device for a motion sensor movably arranged in a receptacle which can be rotated about a shaft, the deflection of the motion sensor from an initial position being detected and measured. The motiond detector has, on a side facing the rotating shaft of the receptacle, a scale provided with different optical characteristics in code form. In an axial bore of the rotating shaft, at least one fiber-optical light guide is arranged, one end of which is directed to the scale and the other end of which is directed to an electro-optic component, the electro-optic component being fixedly connected with a housing part bearing the rotating shaft of the receptacle.
