Sensitive broad band alternating magnetic field detector, and its use as a measuring apparatus
Abstract
Abstract Translated from French Dispositif permettant d'accroître les performances notamment des points de vue sensibilité et bande de fréquence. Il comporte un bobinage hélicoïdal (1) en structure coaxiale, adaptée aux extrémités de raccordement à un appareil de mesure annexe (4). A chaque spire une portion démunie du conducteur extérieur (3) est ménagée et équipée d'éléments d'adaptation à la valeur d'impédance caractéristique (Zc) pour compenser les ruptures ainsi causées. Device making it possible to increase the performances in particular from the point of view of sensitivity and frequency band. It comprises a helical winding (1) in coaxial structure, adapted to the ends of connection to an additional measuring device (4). At each turn a stripped portion of the external conductor (3) is provided and fitted with elements for adaptation to the characteristic impedance value (Zc) to compensate for the breaks thus caused.
