Abstract

L'invention concerne un appareil ou << furet >> entraîné dans le courant de matière transporté par un pipeline et qui est muni d'un équipement pour détecter, amplifier, sélectionner et enregistrer les signaux acoustiques émis par les fuites ou par des sources externes de vibrations codées. L'appareil comporte un amplificateur 4 à coefficient d'amplification variable dont l'entrée de réglage du coefficient d'amplification est raccordée à la sortie du sélecteur du signal des sources externes, la sortie de l'amplificateur étant raccordée à des circuits complémentaires de traitement et d'enregistrement de l'appareil. L'invention permet d'améliorer la détection des signaux des sources externes de vibrations codées et de prolonger ainsi la durée de vie utile de telles sources.
