Abstract

L'invention concerne un montage pour un détecteur de déplacements à ultrasons, notamment pour la commande sans contact d'un robinet d'eau. Dans ce montage, qui comporte un circuit de réception 31 muni d'un discriminateur de phase 32 identifiant la valeur d'un déphasage dans une tension alternative 33 et le signal reçu ainsi qu'un circuit de mémoire 35 et un circuit d'exploitation 38, seuls de brefs trains d'ondes de rayonnement ultrasonore sont émis, avec mémorisation des valeurs des déphasages, qui sont interrogées périodiquement, le circuit 38 comportant un circuit comparateur 39 comparant les valeurs mémorisées en vue de fournir un signal de déclenchement 41 lors de la présence d'un objet mobile. Application notamment à la commande automatique sans contact de robinets d'installation d'eau chaude
