A device for evaluating a measured quantity obtained on a rotating shaft comprises an angle of rotation-converting device (2-6; 21-23) for converting a measured quantity to an angle of rotation and a recording device (12) for deriving the measured quantity from the angle of rotation. The measured quantity can be determined digitally with high resolution. To this end, the recording device has a pulse signal source (13) and a sensor (10, 11). The sensor (10, 11) comprises a first counting circuit, which counts the pulses from the first pulse signal source (13) during a relative movement corresponding to the angle or rotation, and a second counting circuit (15), which counts reference pulses during rotation of the shaft through a reference angle. The recording device (12) derives the measured quantity from the quotient of the counter readings. |
