Abstract
A scale and related method for a length-measuring system for recording the absolute values of angles or distances. The scale includes a printed circuit board, at least one track for identifying length information or angle information and a coding for identifying the scale. The coding has at least one coding element comprising at least two electrodes and a conductive connection between the electrodes on an insulator substrate. The electrical connection is configured to be irreversibly destroyed when an electrical current is applied.

A scale for a length-measuring system for recording the absolute values of angles or distances, the scale comprising:
- (a) a printed circuit board including at least one track for identifying length information or angle information;
- and (b) a coding for identifying the scale, the coding having at least one coding element with at least two electrodes and a conductive connection between the electrodes on an insulator substrate, wherein the electrical connection is configured to be irreversibly destroyed by applying an electrical current.
A length-measuring system for recording the absolute values of angles or distances comprising:
- a plurality of scales arranged next to each other and each scale including (a) a printed circuit board with at least one track for identifying length information or angle information;
- and (b) coding for identifying each scale, the coding having at least one coding element with at least two electrodes and a conductive connection between the electrodes on an insulator substrate;
- a first sensor unit having at least one sensor for recording the length or angle data of each of the plurality of scales;
- wherein the length information or angle information on the at least one track of each scale are identical;
- and the coding of each scale of the length-measuring system is configured in such a way that it differs from another scale by at least one coding element.
A method for the production of a length-measuring system for recording the absolute values of angles or distances, the method comprising:
- providing a plurality of identical scales, each scale including (a) a printed circuit board with at least one track for identifying length information or angle information;
- and (b) a coding for identifying each scale, the coding having at least one coding element with at least two electrodes and a conductive connection between the electrodes on an insulator substrate, the length information or angle information on the at least one track of each scale and the coding elements of each scale of the length-measuring system are identical;
- arranging the plurality of scales next to each other;
- and
- identifying each of the plurality of scales by the selective application of a current to at least one coding element, so that each of the plurality of scales comprises a different coding.
