Position measuring device and method for mounting a scanning element of a position measuring device

摘要

The device uses a non-indicating measuring device or indexing scale (3) which is scanned by a scanning head (5) of a scanner (4). The scale is fixed to a first object (1), e.g.a motor shaft, and the scanner to a second object (2) using a mounting fixture (6). The scanner is fitted with an position adjustment screw (9) to move the scanning head from a first reference position to a second reference position. This enables the clearance between the measurement scale and scanning head to be set at a specific value
