length measurement

Length measurement

The enclosed grating ruler is an ideal choice for cutting fluids that can effectively prevent dust, chips, and splashes in machine tools.

There is no mechanical contact between the open grating ruler and the reading head, grating ruler or steel strip. The typical applications of these grating rulers include measuring machines, comparators, and other precision length measuring equipment, as well as production and measurement equipment, such as those used in the semiconductor industry.

The incremental grating ruler determines the current position by counting the number of measurement steps or counting signals from the subdivision circuit starting from the origin. Heidenhain's incremental grating ruler comes with a reference point, which must be reset to zero when turned on, making the operation very simple and fast.

The absolute grating ruler can directly provide the current position value without performing a reference point zeroing operation. The absolute position value of the grating ruler is transmitted through the EnDat interface or other serial interfaces.
