Zusammenfassung

Auf Laufzeitmessung basierende Ultraschallsensoren werden vielfach in der Prozessüberwachung eingesetzt. Viele Prozesse beinhalten Mehrkomponentensysteme mit speziellen Anforderungen an die eingesetzte Sensorik. In diesem Beitrag werden ein neuartiger Dichtesensor und ein Ultraschalltomographie-System vorgestellt, die sich speziell für solche Prozesse eignen.

Summary

Ultrasonic sensors based on time-of-flight measurements of acoustic waves are employed for the solution of various measurement tasks in the process industries. Many processes contain multiple component fluid mixtures, posing special requirements on the instrumentation. We present a novel density sensor and a reflection tomography system aimed at such processes.
