Abstract

Ermitteln des Schwingungszustandes von in einer Strömungsmaschine mit an einer in einem Gehäuse drehbar gelagerten Rotorwelle angeordneten Laufschaufeln (4) und/oder Leitschaufeln. Durch Mittel (8) zum Erzeugen mindestens einer elektromagnetische Welle (31) in einem Strömungskanal in einem Bereich der Schaufeln (4) ausgesendet. Die elektromagnetische Welle wird von wenigstens einer Schaufel (4) zumindest teilweise reflektiert. Der reflektierte Teil wird durch Mittel zum Empfang (8) empfangen und aus einem entsprechenden Signal wird der Schwingungszustand der jeweiligen Schaufeln (4) ermittelt.
