ABSTRACT:
A position measuring device having a scanning element assigned to a periodic measuring graduation, the scanning element moves relative to the measuring graduation so as to scan the measuring graduation and generates a first analog signal and a second analog signal that is phase shifted relative to the first analog signal. A module that forms a measured position value, wherein the first and second analog signals are present at the module, and a code word defines a position that is present at an output of the module. An output module that digitally outputs the code word over a data channel and a conversion device that converts the first analog signal and the second analog signal into multi-digit amplitude-proportional code words, wherein the code words are also available at the output module for outputting on the data channel and is digitally transmitted by the output module over the data channel.
