Abstract
An arrangement for angular measurement includes an angle sensor that supplies sensor signals phase shifted 90° with respect to each other and having actual amplitude values. A signal-processing device provides expected amplitude values of the sensor signals and graded limit values for a deviation between the expected amplitude values and the actual amplitude values of the sensor signals; compares the expected amplitude values with the actual amplitude values of the sensor signals; determines a deviation between the expected amplitude values and the actual amplitude values, and a range of values in which the determined deviation occurs; and generates an error signal including reliability class information about the range of values in which the determined deviation occurs. As a result, monitoring and evaluation of the measured sensor signals with accuracy and reliability is possible.
