A process and device for determining absolute position by means of two coupled individual sensors which in the measuring range generate saw tooth-shaped output signals with a number of periods (k1 and k2) varying by "1," and use of a third sensor, which in the measuring range also generates a saw tooth-shaped output sign with a third number of periods (k3) in which k3 differs from k1 and k2 by the absolute value ½. If the first or second sensor fails, a differential signal is generated between the output signal of the remaining functional sensor and the third sensor.
