Process and incremental transducer for determining an actual position of a body along a measuring path of a material measure having at least one gap
First Claim
1. A process for determining an actual position of a body along a measuring path and/or a change in a position of the body along the measuring path, the process comprising the steps of:
- scanning a position code having a plurality of position markers arranged with a predetermined actual location frequency and having at least one gap between ends of said position code;
generating a position signal representative of an actual position and/or a change in the actual position of the position code, wherein to generate the position signal, the actual location frequency is converted into a desired location frequency that is independent from a length of the gap.

Abstract
An incremental transducer (1) as well as a process (D1) are provided for determining an actual position of a body (5) along a measuring path (W) and/or a change therein. A position code (7) of the incremental transducer (1) has a gap (10). To make it possible to use the incremental transducer (1) as flexibly as possible and to operate it despite dimensional tolerances of the body (5), provisions are made for converting an actual location frequency (Fi) of the position code (7) into a desired location frequency (Fs) that is independent from the length (L) of the gap (10) to generate a position signal (S) representative of the actual position or the change therein.

-
a measured material element, which extends along the measuring path and which is interrupted by at least one gap and is provided with a position code having a plurality of position markers arranged along the measuring path with a preset actual location frequency; a position signal generator, of the incremental transducer that sends a position signal representative of the actual position and/or change in position of the body along the measuring path during an operation, including two sensor arrays for scanning the position code, said two sensor arrays being arranged at spaced locations from one another along the measuring path such that at least one of said two sensor arrays is always arranged outside of the gap during operation; and a conversion unit, by which the actual location frequency scanned by the two sensor arrays is converted into a desired location frequency. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A measured material element that can be arranged along a measuring path for an incremental transducer, the measured material element comprising:
-
a position code with a plurality of position markers arranged along the measured material element, the position markers having a preset actual location frequency, the measured material element having ends and being applied for operation of an incremental transducer with at least one gap between said ends; a connection device for connecting said ends of the measured material element adjoining the gap to one another, said connection device being elastically compliant at least partly along the measured material element in a state in which said connection device is captively connected to said ends.
