  • Accuracy or repeatability - which does my system need?

    2020-6-22 · Linear encoder is a sensor or transducer that measures linear movement of an object. The device can move in different directions but always travels along one axis. It can detect speed, distance, direction, and displacement. However, there is a special type that works with the use of this method with diameters or round objects.
