Abstract

A device for determining an absolute angle of rotation of a rotational axis has a first measuring device for measuring an angle of rotation in a limited first measuring range and a second measuring device for determining an absolute angle range. The second measuring device transforms a rotation of the rotational axis into a linear shift.
