Disclosed is a measuring element (10) comprising a circular or linear track (12) that encompasses a material measure, and a number of sensors for scanning the track (12). At least two scanning heads (18, 19, 20, 22, 23, 24) comprising the sensors are provided for scanning the track (12). The track (12) of the measuring element (10) has at least one first and a second partial track (14, 16) which are each provided with a first and a second grating period. For each grating period, one of the scanning heads (18, 19, 20; 22, 23, 24) is equipped with a sensor array that is adjusted to said grating period. |
