Patent attributes
An angle measuring device includes first and second component groups and a bearing. The first component group includes a scale element having first and second graduations. The second component group has a first modular unit, having a position sensor, a second modular unit, having first to sixth position transducers, and a compensation coupling. To determine the relative angular position between the component groups, the first graduation is scannable with the aid of the position sensor. Using the first to third position transducers, the first graduation or a further graduation disposed on the scale element is scannable to determine a displacement of the scale element in a plane. Using the fourth to sixth position transducers, the second graduation is scannable to determine tilting of the scale element about a tilting axis, the position sensor being situated in a torsionally stiff but axially and radially flexible manner relative to the position transducers.
