4. PRINCIPLES OF OPERATION
The ultrasonic power supply transforms AC line power to a 20 KHz signal that drives a
piezoelectric converter/transducer. This electrical signal is converted by the transducer to a
mechanical vibration due to the characteristics of the internal piezoelectric crystals.
The vibration is amplified and transmitted down the length of the horn/probe where the tip
longitudinally expands and contracts. The distance the tip travels is dependent on the
amplitude selected by the user through the keypad. As you increase the amplitude setting the
ultrasonic processing intensity will increase within your sample.
In liquid, the rapid vibration of the tip causes cavitation, the formation and violent collapse of
microscopic bubbles. The collapse of thousands of cavitation bubbles releases tremendous
energy in the cavitation field. The erosion and shock effect of the collapse of the cavitation
bubble is the primary mechanism of fluid processing.
The probe tip diameter dictates the amount of sample that can be effectively processed.
Smaller tip diameters probes deliver high intensity ultrasonic processing but the energy is
focused within a small, concentrated area. Larger tip diameters can process larger volumes,
but offer lower intensity.
The choices of a power supply and horns/probes are matched to the volume, viscosity and other
parameters of the particular application.
Please consult with a product specialist for assistance with selecting a probe for your
application.
Relationship of Amplitude and Wattage
Ultrasonic processing power is measured in watts. Amplitude is a measurement of the
excursion of the tip of the probe (probe is also known as a horn).
Some ultrasonic processors have a wattage display. During operation, the wattage displayed is
the energy required to drive the radiating face of a probe, at that specific amplitude setting
against a specific load, at that particular moment. For example, the unit experiences a higher
load when processing viscous samples then when compared to aqueous samples.
The speed/cruise control on an automobile, can, to a certain extent, be compared to an
ultrasonic processor. The speed/cruise control is designed to ensure that the vehicle maintains
a constant rate of travel. As the terrain elevations change, so do the power requirements. The
cruise control senses these requirements, and automatically adjusts the amount of power
delivered by the engine in order to compensate for these ever changing conditions. The greater
the terrain rate of incline and greater the resistance to the movement of the vehicle, the greater
the amount of power that will be delivered by the engine to overcome that resistance and
maintain a constant speed.
The ultrasonic processor was designed to deliver constant amplitude to your liquid sample,
regardless of these changes in load (much like the vehicle’s cruise control described above).
As a liquid is processed, the load on the probe will vary due to changes in the liquid sample (i.e.
viscosity, concentration, temperature, etc.). As the resistance to the movement of the probe
increases (increased load on the probe), additional power will be delivered by the power supply

Page 8 of 30
to ensure that the excursion at the probe tip remains constant. The displayed wattage readings
will vary as the load changes; however, the amplitude will remain the same.
The resistance to the movement of the probe determines how much power will be delivered to
maintain amplitude. The wattage required to operate the probe will increase as the load
increases but the amplitude remains the same.
The amplitude control allows the ultrasonic vibrations at the probe tip to be set to any desired
level. Although the degree of cavitation/ultrasonic energy required to process the sample can
readily be determined by visual observation, the amount of power required cannot be
predetermined. A sensing network continuously monitors the output requirements, and
automatically adjusts the power to maintain the amplitude at the preselected level. The greater
the resistance to the movement of the probe due to higher viscosity, deeper immersion of the
probe into the sample, larger probe diameter or higher pressure, the greater the amount of
power that will be delivered to the probe. Setting the amplitude control to its maximum will not
cause the maximum power rating of the unit to be delivered to the sample. The maximum power
that the Processor is capable of delivering will only be delivered when the resistance to the
movement of the probe is high enough to draw maximum wattage.
It is the intensity of cavitation that measures the effectiveness of the ultrasonic processing, not
the total power applied to the system. Intensity is directly related to the amplitude of the
radiating face of the tip or horn. It is amplitude that must be provided, maintained, and
monitored. The unit provides controlled amplitude under varying load conditions in order to give
reproducible results.

5. INSTALLATION
5.1. INSPECTION
Prior to installing the Ultrasonic Processor, perform a visual inspection to detect any evidence of
damage, which might have occurred during shipment. Before disposing of any packaging material,
check it carefully for small items.
The equipment was thoroughly inspected and carefully packed before leaving our factory. The
carrier, upon acceptance of the shipment, assumed responsibility for its safe delivery. Claims for
loss or damage sustained in transit must be submitted to the carrier.
If damage has occurred, contact your carrier within 48 hours of the delivery date. DO NOT
OPERATE DAMAGED EQUIPMENT. Retain all packing materials for future shipment.
5.2. ELECTRICAL REQUIREMENTS
The Ultrasonic Processor requires a fused, single phase 3-terminal grounding type electrical outlet
capable of supplying 230 +/- 10% VAC, 50/60 Hz, 30 amps.
If the desired plug type is different for your country or region see the wiring diagram below:
WARNING
For your personal safety, do not, under
any circumstances, defeat the grounding
feature of the power cord by removing the
grounding prong.

5.3. INSTALLING THE ULTRASONIC PROCESSOR
The ultrasonic processor should be installed in an area that is free from excessive dust, dirt,
explosive and corrosive fumes, and extremes of temperature and humidity. If processing
flammable liquids, use an approved fume hood and do not place the power supply in the fume
hood.
Unit shall be placed on a flat clean level surface. The mounting feet shall not be removed from
the bottom of the unit. The unit vents through the holes in the chassis located on the underside of
the unit. Keep this area clear of debris and dust.
When positioning the unit, be sure to leave adequate space behind the unit so that all
connections can be easily disconnected. Verify the fan on the rear of the unit is rotating and
operational.

Page 11 of 30
5.4. CONVERTER COOLING
The nature of sonication causes the probe, converter and sample temperature to increase
during operation. Processing samples requires significant amounts of energy and some of this
energy manifests as heat in the converter and probe. The converter contains sensitive internal
crystals which can crack due to overheating, which would require the converter to be replaced.
Converter damage due to overheating is not covered under warranty. Air cooling using
compressed air is required to always keep the converter within safe operating temperatures.
The elements of the system will still heat up when air cooling is employed, but the converter will
operate at an acceptable temperature for continuous use. It is important to note that your
sample liquid may also require cooling, using an ice bath, heat exchanger or a chiller. Cooling
both the sample and the converter will ensure safe operation.
Instructions:
Connect your compressed air source to the hose barb fitting on the top of the converter with 1/4”
ID tubing.
The compressed air source must meet the following specification:
 3-4 cubic feet per minute (CFM)
 10 psig ±1
 70°F
 Dry
 Oil free
 Filtered with a 5 micron filter
Any deviation from the above compressed air specifications may
void the warranty.

6.4. PROBE DETAILS
Proper setup is important to optimizing the sonication amplitude settings and
processing times. The probe should be securely held using the #830-00461 stand
and clamp This clamp can be secured to either the booster ring or bottom of the
converter.
Probe depth must be adjusted to ensure adequate mixing and sample circulation.
Larger volumes and viscous samples will process more quickly and effectively with
the addition of a mixer or stir bar.

7. OPERATING INSTRUCTIONS
7.1. CAUTION
 Do not operate the power supply unless it is connected to the converter.
 Never allow liquid to spill into the converter.
 Never place a washer between the probe and the converter.
 Never apply grease to the mating surfaces or threads of the converter or microtip.
 Should it become necessary to remove a probe, use the wrenches supplied. Never attempt
to remove the probe by twisting the converter housing, as this may damage the electrical
connections within the housing.
 Overheating will damage the converter. If continuous operation for more than 15 minutes is
required, see addendum for converter cooling instructions.
 The converter should remain near room temperature at all times. The sample liquid
temperature should not exceed 60C (140F). If either of these temperature limits are
reached, shut the system off and allow it to cool.
7.2. SETUP
1. Make sure the unit is switched off. Plug the electrical line cord into the electrical outlet.
2. If the optional foot switch is used, insert the plug into the jack located on the rear panel.
3. For best results it is critical to use the appropriate size and type of accessory to
process your sample. If you are not sure that you have the proper horn for your sample
volume, please refer to the product brochure or call for assistance.
4. Horns/Probes must be properly tightened. Depending on the accessories purchased,
often the horn and the flat tip are attached to the converter at the factory. Check the
tightness of the horn and flat tip by using the wrench set. Please refer to images in the
Maintenance section of this manual. A loose horn or tip may cause damage to the power
supply circuitry or parts of the converter and horn. A loose horn may also show a fluctuation
in wattage readings. Always use the wrenches supplied with the unit.
5. Horns and probe tips wear after normal usage. Using a severely worn probe tip can
damage internal power supply components.
6. If using a laboratory stand, mount the converter /probe assembly using a clamp. Be sure to
secure the clamp to the upper section of the converter housing only. Never secure the
clamp to any other portion of the converter/probe assembly. If you are using an acoustic
enclosure mount the converter properly in the converter collar.

7.3. OPERATION
START UP: Press the ON key. The screen will display the power rating of the Ultrasonic
Processor and the following control parameters.
AMPLITUDE: Desired amplitude must be set in order for the Ultrasonic Processor to be
operational. The other control parameters – Time and Pulse, do not have to be set for
continuous operation. AMPL displays the percentage of amplitude that was previously selected.
To set the amplitude at 40%, when the ultrasonics is off, press the AMPL key and the numeric
keys for a 40% reading on the screen, and then press the ENTER/REVIEW key. (Pressing the
AMPL key and the ▲ or ▼ key for a reading of 40% and then pressing the ENTER/REVIEW
key, will also achieve the same result.)
Note: The minimum amplitude setting is 20%.
The screen will display:
1. Immerse the probe approximately halfway into the sample. If the probe is immersed to an
insufficient depth, air will be injected into the sample, causing the sample to foam. Also
ensure that the probe tip is not touching the wall of the sample vessel.
2. The Ultrasonic Processor is now ready for continuous operation. To energize the
ultrasonics, press the START key or the footswitch. To de-energize the ultrasonics, press
the STOP key or release the footswitch. If the Time or Pulse functions must be used, refer
to the appropriate paragraphs below.
Note: The START key and footswitch are mutually exclusive. If the process is initiated by
the START key, the footswitch becomes inoperative. If the process is initiated by the
footswitch, the STOP key becomes inoperative.
3. To increase or decrease the amplitude in small increments when the ultrasonics is on,
depress the AMPL to display Amplitude Setting on the screen, then depress the ▲ or ▼
key, as required. Since the amplitude required is application dependent and subject to the
volume and composition of the sample, it is recommended that the amplitude be selected
through experimentation, by increasing or decreasing the level of intensity as needed to
properly process the sample to achieve desired results.
4. Be sure to use the fittings provided, for the top of the Converter, for air cooling if necessary.
Circulate clean dry compressed air through the Converter to cool the Converter during use.
See manual addendum for more information.
TIMER: In the pulsed mode the processing time will be different from the elapsed time because
the processing time function monitors and controls only the ON portion of the duty cycle. For
