Abstract

L'électrode pour la meme de la permittivite relative lectrode (14) ainsi que n (nombre pair) éléments d'électrode (12) arrangés coaxilament avec ce corps et espacés en sorte que leurs surfaces périphériques, en meme temps que les surfaces périphériques adjacentes du corps d'électrode, forment une surface plate à l'extérieur de l'électrode (10), faisant face directement à l'atmosphère ambiante, la matière (18) du corps d'électrode entre les éléments d'électrode étant électriquement isolante, et les fils d'amenée (20, 22) d'éléments d'électrode voisines pouvant etre connectés en paires pour la mesure.
