Abstract

L'invention a pour objet un avertisseur accoustique de profondeur comportant : un sondeur capable de générer des impulsions haute fréquence et une sonde capable de rayonner lesdites impulsions et de recevoir les impulsions d'écho correspondantes, caractérisé par le fait que ce sondeur est pourvu de moyens électroniques capables de coder la mesure desdits intervalles de temps, de moyens électroniques capables de comparer le nombre exprimé de ladite mesure, avec un nombre prédéterminé et de moyens de transposition électro-acoustique reliés auxdits moyens de comparaison et de codage, capables de produire une signalisation acoustique codée. L'invention s'applique aux sondeurs de navigation.
