Monitor Your Ultrasonic Cleaner: Introducing Our Externally Mounted Cavitation Monitoring Sensor (CMS). Our externally positioned Cavitation Monitoring Sensor (CMS) offers a solution for unobtrusive, continuous observation of cavitation performance within your ultrasonic tank.

The OptiSon® Beam Analyzer quantifies beam plots, focal distances and total power from a single image. Power measurements correlate to radiation force balance and hydrophone - as does tomographic reconstruction for intensity. It can have higher spatial resolution than mechanical scanning and is invulnerable to high intensities or rough handling.

The MCT-2000 combines the power of a high speed digitizer, spectrum analyzer, and advanced microprocessor to produce an acoustic pressure spectrum. Different components in the spectrum are analyzed to quantify the fundamental frequency and pressure from the direct field, stable cavitation, and transient cavitation. Specifically, the pressure within the fundamental frequency peak represent the direct field pressure from the sound wave. The harmonics, sub-harmonics, and ultra-harmonics represent the stable cavitation, or the cavities that oscillate in size and dimension. Finally, the broadband white noise in the spectrum represent the transient cavitation, or the cavities that implode and collapse.

The HCT hydrophone with MCT-1200 Digital Pressure Meter is a trustworthy instrument to characterize and monitor the relative acoustic cavitation in ultrasonic cleaning systems. Its unique single point sensing design allows localized measurements to generate true 3-cimensional acoustic maps of the cleaning tank.

Onda develops and manufactures innovative OEM cavitation sensors for integration into ultrasonic cleaning systems to continuously or routinely monitor the acoustic stability. The integrated sensor technology leverages from extensive experience developing and manufacturing hydrophones used for various industrial and medical applications.

The CTS Scanner enables hydrophone mapping to be done automatically, using the HCT hydrophone. The scanner is customized to mount to substrate carriers, eliminating the need for positioning alignment. Because the shaft diameter of the HCT hydrophone is only ~3 mm, 2D acoustic plots can be acquired in “loaded” configurations to simulate actual conditions in the cleaning process (e.g., between substrates for semiconductors, data storage, and related applications).
