Digital detection of spindle encoder！

Digital detection is quantified by the unit of measurement after the digital form. Measurement signal is generally electrical pulse, you can directly send it to the CNC system for comparison, processing. Such a detection device has a pulse encoder, a grating. Digital detection has the following three characteristics.
① measured into the number of pulses, easy to display and deal with;
② measurement accuracy depends on the measurement unit, and the scale has nothing to do; but there is cumulative error error;
③ detection device is relatively simple, pulse signal anti-interference ability.absolute encoder, incremental encoder, spindle encoder,digital encoder,
