In many cases ultrasound induced cavitation is the main reason for these enhancements. Therefore, it is desired to quantify cavitation activity during the process to optimize sonication for various processes and monitor cavitation activity throughout the process. One possibility to monitor cavitation activity is to measure the acoustic emissions of oscillating and collapsing cavitation bubbles by hydrophones in the liquid. However, harsh environments often coming along with chemical processes complicate the application of sensors in the liquid. Thus, this contribution discusses the applicability of the feedback of cavitation on the driving signals of the ultrasound transducer itself as possible alternative for cavitation monitoring. The measurement results show that the threshold of inertial cavitation could be detected based on the current signal of the transducer. Some indicators can even be used to distinguish between the two types of cavitation. However, to evaluate the strength of cavitation the application of a cavitation sensor is recommended.
