An angle sensor includes at least two angularly spaced sensor units which measure in a contactless manner and whose sensor voltages are similar but angularly shifted sinusoidal functions (sensor characteristic) of the angle alpha to be measured relative to a rotatable element and a processing circuit forms an angle sensor voltage which is a measure of the angle alpha . Using limited analog circuitry, a wide angular range is obtained and also a monotonously increasing angle sensor voltage which is dependent as linearly as possible on the angle to be measured, in that the sensor voltages are direct voltages which are constant in time. The processing circuit includes limiter circuits (15) whose input receives the sensor voltages (UMA, UMB), and whose output voltages exhibit values (10, 11) which remain constant when a limit value of the sensor voltages is exceeded, and that the output voltages of the limiter circuits (15) are applied to the input of a summing circuit (16) in order to form the angle sensor voltage.
