Abstract
Besides the measurement of angular position, an angular measurement system having an integrated Ferraris sensor also permits the direct measurement of angular acceleration or angular velocity. A graduated disk and an eddy-current disk are configured concentrically in one plane. Relief elements may ensure that temperature variations do not cause the connection between the graduated disk and the eddy-current disk to be lost.
