Abstract
Casse-fil capacitif indiquant avec précision la présence d'un fil en mouvement en émettant un signal approprié, lequel signal est interrompu en l'absence d'un fil en mouvement, caractérisé en ce que le fil à contrôler 15 traverse un condensateur de mesure 10 dans lequel il constitue un élément dans la zone diélectrique, et en ce que le condensateur de mesure 10 est relié, d'une part, à une source de tension continue 11 établissant un champ électrique, et, d'autre part, à un amplificateur 14 à haute résistance d'entrée.
