Abstract
a. Sonde capacitive pour la mesure de petits intervalles entre une surface de mesure et la surface externe d'un matériau conducteur. b. Sonde caractérisée en ce qu'à l'intérieur d'un blindage fermé à la partie supérieure et à l'extrémité inférieure de celui-ci, se trouve une première électrode se terminant avec le blindage, une seconde électrode étant disposée au-dessus de cette première électrode, une broche de couplage avec une surface de mesure étant située dans une ouverture de la première électrode et, éventuellement, dans une cavité de la seconde électrode avec sa surface de mesure affleurant le blindage et la première électrode, l'espace intermédiaire entre le blindage, les électrodes et la broche de couplage étant rempli avec un diélectrique. c. L'invention s'applique notamment à la détection des contours d'un matériau conducteur.
