Hydrophone for Ultrasonic Power Measurement
Ultrasonic cleaning systems are currently used in a wide variety of industries. In all cleaning applications, it is important to control ultrasonic power to match your desire cleaning result.
Excessive ultrasonic power can cause damage to your delicate product, while too little of ultrasonic power will not deliver your expected level of cleaning. Our hydrophone set provide you with the visibility of the power of your ultrasonic cleaning system.

PPB Megasonics Products
Since 1996, ppb has been the leader in providing solutions to your Ultrasonic
and Megasonic cleaning efficiency concerns. With ever decreasing dimensions or need for quality assurance,
the understanding and analysis of your cleaners has never been more critical.
Our advanced line of cavitation metrology
instruments have been proven to increase yield by accurately measuring the
energy and frequency in Ultrasonic and Megasonic cleaning baths, nozzle
streams and films, and cell disruptors and
Our digital hand-held meters allow users to map the in-situ energy distribution, establish tank-to-tank uniformity, and
identify de-bonded or failed transducers. This is accomplished through our
advance sensor and signal processing design, which captures the cavitation
implosion and the driving acoustic signatures.
Our probes provide an accurate and repeatable measure that incorporates
such solution variables as temperature, vapor pressure, surface tension, and flow
rate. Continuos monitoring is also possible with our Monitoring-Transmitter. NIST Traceable Calibration available.
and Cell Disruption
by Lawrence Azar
It is important to quantify the cavitation energy in
all applications ranging from ultrasonic cleaners to
cell disruptors. A cavitation meter measures the energy
intensity and frequency within ultrasonic and megasonic cleaners,
including probes with side-mounted sensors that can be placed within the
megasonic jet streams and single wafer cleaners, as well as those
resembling a beaker to quantify the energy emanating from the ultrasonic
horns used for cell disruption and homogenizing.
Understanding and Evaluating
Ultrasonic and Megasonic Cleaners
by Lawrence Azar
Achieving perfect uniformity within a bath has been elusive
and assuring one is operating between effective levels is
critical. Using the cavitation meter as a process control tool
will improve both the yield and throughput of the cleaning
Comparison the cavitation meter and hydrophone
by Tewarit Seemakan
The cavitation meter then outputs the
RMS of the cavitation energy intensity (units of watts
per square inch) and the frequency of the ultrasound.
These meters are not hydrophones, which typically filter
out the higher frequency cavitation signatures and
inherently spatially average compression and rarefaction
resulting in misleading data. The cavitation
signature is superimposed on the acoustic measure, but
has no spatial average component. The acoustic signature is removed, compression and rarefaction, leaving
behind only the cavitation implosion forces.
