The advanced MCT-2000 acoustic cavitation meter addresses the critical need to quantify the cavitation performance used in ultrasonic cleaning and sonoprocessing applications. Coupled with a calibrated HCT-0320 hydrophone, four key parameters are determined instantaneously :
- Fundamental Frequency, FO
- Direct Field Pressure, PO
- Stable Cavitation Pressure, PS
- Transient Cavitation Pressure, PT
This is done by analyzing the calibrated acoustic spectrum which captures different pressure components. Mechanical sound waves induced by transducers oscillating at the fundamental frequency generate the direct field pressure. Rapid changes in pressure within the liquid create cavities or “cavitation”. Stable cavitation represents a cavity oscillating in size and shape, resulting in micro-streaming effects. Transient cavitation occurs beyond a pressure threshold, where the cavities collapse creating jetting effects and shockwaves.
