Abstract
a. Système de détection et de classification des criques de surfaces métalliques. b. Système caractérisé en ce qu'il comporte un moyen pour diviser chaque signal de balayage en série fourni par le premier et le second capteurs en plusieurs échantillons, des moyens pour combiner les échantillons, un premier comparateur pour comparer chaque échantillon d'un signal de balayage en série du premier capteur, un second comparateur pour comparer chaque échantillon d'un signal de balayage série du second capteur, ainsi qu'un analyseur pour créer un troisième signal. c. L'invention trouve son application principale dans la technique de fabrication de tubes pour réacteurs nucléaires.
