Abstract
L'invention concerne un montage pour une installation à ultrasons de protection contre les risques d'effraction, fonctionnant selon le principe de l'effet Doppler. Ce montage comporte un transducteur de réception 3 raccordé à un circuit d'exploitation 7 par un amplificateur 4, un détecteur de phase 5 et un filtre passe-bas 10, et un transducteur d'émission 2 relié à un circuit à boucle à phase bloquée comportant un second détecteur de phase 9, un filtre passe-bas, un amplificateur il et un oscillateur 110, dont la fréquence peut être commandée par une entrée de commande 102, le filtre 10 ne laissant passer sans affaiblissement que des signaux dont la fréquence est inférieure à une fréquence critique déterminée. Application notamment aux systèmes d'alarme à détection d'intrus.
