PROBLEM TO BE SOLVED: To provide an angle-measuring device, that is improved to a range for monitoring operation safely. SOLUTION: This angle-measuring device, that measures angle by an angle sensor (1) for supplying two sensor signals having an amplitude that depends on temperature, while phases mutually shifted by 90 degrees generates an error signal, and is provided with a temperature sensor (7) and a microprocessor (6), The microprocessor (6) measures an angle by the angle sensor (1) for calculating the amplitude values of the sensor signal that is predicted, depending on a temperature value that is supplied from the temperature sensor (7), compares the values with the actual amplitude value of the sensor signal, and generates an error signal, when the difference between the predicted amplitude value and the actual amplitude value exceeds a specified limiting value.
