Vibration pick-up unit, e.g. for a harvester/reaper, especially a field chopper, has a casing with a vibration pick-up and signal-processing circuits

摘要

A casing (66) holds a vibration pick-up (76) and a signal-processing circuit (88) to handle digital signals and to link to a signal output on the vibration pick-up unit and to a digital interface (98) using signals from the vibration pick-up unit to transfer data on a machine element's condition. An independent claim is also included for a harvester/reaper, especially a field chopper, with a vibration pick-up device.
