Part detection or testing for industrial automation process - using ultrasonic echo signal evaluation with transmitted signals matched to reflection signals of specific parts

摘要

A method of detecting or checking parts using ultrasonic echo signal evaluation involves transmitting at least one short duration, wideband ultrasonic signal towards the part over an air path contg. at least one ultrasonic transmitter and receiver and evaluating the reflected signal. The transmitted signal is a stimulation signal matched to the part's reflection profile so that the echo signal has a specific needle pulse shape if a part is present. USE/ADVANTAGE - Detecting or checking parts for industrial automation purposes. Previously introduced parts can be rapidly differentiated and checked for defects.
