Abstract
An indicating system for measuring movement of a material, having a magnetic pickup device, waveform conditioning circuit and light signal emitter functioning under the system's own self-made power, having a light waveguide or optic fiber connecting the light signal emitter to a light signal receiver which in turn is connected to a signal processor for outputting information such as speed, acceleration and/or position of the material.
