Measuring object absolute position measuring device, has sensor head with sampling unit reading absolute coding of partitions of solid measure and sensor that detects permanent magnetic markings

摘要

The device has a sensor head for scanning the solid measure (10). The solid measure has partitions (4) that are closely adjacent to one another in a measuring direction, where partitions respectively form an absolutely coded measuring section. The sensor head has a sampling unit that reads the absolute coding of the partitions and a sensor (6) that detects permanent magnetic markings (5). The sensor has a wire (7) that is influenced by the permanent magnetic markings.
