Abstract

a. L'invention concerne un montage permettant la commande automatique de la fréquence d'un transducteur d'émission à ultrasons. b. Ce montage contient un circuit d'adaptation automatique de fréquence d'un oscillateur 233, qui comprend un générateur de préimpulsions 51 et un discriminateur de phase, reliés à un amplificateur de puissance 44 raccordé à un générateur central de cadence PLL, 145 et à un générateur de cadence d'émission 142, en vue de comparer les phases de l'oscillation d'amortissement du transducteur d'émission et de l'oscillation de l'oscillateur à commander. c. Application notamment aux systèmes de commande de robinets d'eau.
