Resonant cells are described for ultrasonic measurements in liquids. An automatic system uses a microprocessor to carry out the operational process and to handle the acquired results. Their construction and performance are described. The use of the system is illustrated by reference to measurements of absorption in aqueous solutions of tubuline.

Sommaire

Des cellules résonnantes ont été mises au point pour des mesures de l'absorption ultrasonore dans les liquides. Un dispositif automatique utilisant un microprocesseur permet de gérer le processus opératoire et de traiter les résultats acquis. Leur construction et leurs performances sont décrites. Des mesures réalisées dans des solutions de tubuline illustrent l'utilisation de ce dispositif.

Zusammenfassung

Für Messungen der Ultraschallabsorption in Flüssigkeiten sind Resonatorzellen aufgebaut worden. Eine automatische Vorrichtung unter Verwendung eines Mikroprozessors erlaubt die Durchführung der Messung und die Verarbeitung der erhaltenen Ergebnisse. Ihre Konstruktion und Funktion wird beschrieben. Ausgefiihrte Messungen an Tubulinlosungen veranschaulichen die Benutzung der Vorrichtung.
