Length measuring device for recycled containers

摘要

The length measuring device has a measuring rod (2) displaced longitudinally within a container reception space (1), under control of an electric motor (3), with a cooperating measuring and evaluation circuit (5) used for determining the length of the container (15) within the reception space from the measuring rod displacement. The measuring and evaluation device may employ a rotary potentiometer (4) for converting the measuring rod displacement into a corresponding electrical value.
