Abstract
L'invention concerne les dispositifs de mesure automatique des dimensions d'un article. Un micromètre optique 10 fournit par la ligne 50 un signal qui traduit le diamètre d'un article cylindrique 20. Le comparateur 30 ne transmet ce signal au dispositif d'affichage 40 que si son écart par rapport aux mesures précédentes ne dépasse pas une limite prédeterminée. Dans le cas contraire, c'est la mesure précédente, ou une moyenne des mesures précédentes, qui est transmise au dispositif d'affichage 40. Application au revêtement de fils métalliques.
