Abstract

La présente invention concerne un tensiomètre de courroie. Le tensiomètre de courroie comprend : un microphone directionnel connecté à un boîtier par l'intermédiaire d'un connecteur de microphone de type écrou ; et une unité de commande formée à l'intérieur du boîtier. L'unité de commande reçoit, par l'intermédiaire du microphone directionnel, la fréquence générée quand une courroie oscille afin de mesurer la tension de la courroie au moyen du microphone directionnel, contrôle le niveau de la valeur d'entrée d'un son en fonction de la fréquence au moyen d'un circuit de tension de polarisation étalonné de manière optimale dans un circuit interne, et permet seulement la capture d'un composant de signal plutôt que d'un composant de bruit à l'entrée du circuit par l'intermédiaire du microphone directionnel.
