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

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

The invention relates to a rotary encoder comprising internal error control with a monitoring unit comprising at least a computing module, a verification means, a memory unit and an alarm unit. The invention also relates to a method for checking a rotary encoder when said encoder is in operation, the rotary encoder generating at least one measuring signal pair representative of the amount of rotation. In order to be able to determine the functioning of the rotary encoder, even when said rotary encoder is stationary, it is provided according to the present invention that a characteristic value should be created in the monitoring unit from current amplitude values of the measuring signal pair, said characteristic value being used in a comparison with at least one quality value representative of the functional states of the rotary encoder.

An absolute value transducer () for determining an absolute position (P) of a body (), with a measured material element (), as well as a process for determining the absolute position (P) of two bodies () in relation to one another. In order to be able to use the absolute value transducer () in as flexible a manner as possible and to detect mounting errors of the measured material element (), provisions are made according to the present invention for a code (K) of the measured material element () to have a discontinuity () in its course and for the code (K) to be scanned outside the discontinuity for determining the absolute position (P) within the discontinuity (), and for the scanned absolute values (W) to be combined with an offset value (A).
