Method for checking size during the passage of bars and device for implementing this method

摘要

The method consists in passing a bar 1 along a passage axis X-X'. Two sensors 3, 4 inclined with respect to each other each form an image of the bar on a bank of photodiodes 11, 12. Electronic supply and processing means 23 allow comparison of the electronic data emitted by the photodiodes and signalling of significant differences. <IMAGE>
