Abstract

Dispositif de mesure de niveau pour diélectriques liquides utilisant le phénomène de résonance. Il comporte une sonde 61-66, 48, 35 dont les parties sensibles 64, 65 présentent en coupe la forme d'un câble d'alimentation, la fréquence de résonance de la sonde étant fonction de la profondeur d'immersion de la sonde dans la matière dont on mesure le niveau. Application à la mesure des niveaux dans l'industrie du pétrole, l'aéronautique et l'industrie chimique.
