The Model L-2000 Ultrasonic power meter consist of a B
Precision Model 5390 True RMS DVM, a coaxial adaptor and a Q-1000
quartz probe. The meter has been pre calibrated at the factory and is
accompanied by a calibration certificate.
HOW IT WORKS:
The tm associates ultrasonic power meter consists of a Quartz Probe
that is immersed in the liquid of the ultrasonic tank. The probe
senses the energy of the actual cavitation collapse generated by your
ultrasonic tank. This energy is translated into a voltage [RMS] that
changes and fluctuates with the amount of energy generated. The
voltage is then amplified and displayed on the meter. A Bar graph on
the bottom of the digital display indicates RMS power fluctuations.
Model Q-1000 18" x.5" dia Quartz Probe
The probe is a .5" dia. high -sensitivity Quartz Sensor for
making cavitation measurements over the frequency range of 20 kHz to
470 kHz it has a high sensitivity relative to its size. It measures
the cavitation in a plain parallel to its surface. This is a
realistic picture of what your part sees as its cleaned. Other
shapes and size probes are available.
Power: [dB/m Watts]
Insert the adaptor in the com / v temp ports of the meter, plug the
probe into the adaptor. Turn on the meter to AC/V and press the
select button [yellow located beneath display] until the display
reads dB/m this gives you the log watts/cmsq power of your
ultrasonics. Set the impedance by pressing range, and toggle to the
correct impedance, this will be displayed on the LCD read out and
will change each time the range button is pushed , when you reach the
correct impedance stop pressing the button and the unit will
automatically go back to dB/m Holding the probe parallel to the
bottom of the ultrasonic tank move it around the tank, you will
notice a change in the reading from place to place and from second to
second. This is due to the erratically fluctuating ultrasonic wave in
the tank. The meter will average out the readings to give a
relativity steady display.
To determine the correct impedance go to the frequency display on the
dial and note the frequency, if for example your tank is a 40 kHz
tank and the frequency reads 65 kHz raise the impedance input as
described above so that the frequency reads 40 kHz. This is the
same impedance you would use for dB/m
RMS [Root Mean Square Voltage]
To read the powers in RMS simply press the select button until Volts
appear on the display. The power will now be read in RMS Volts. The
bar graph will show fluctuations on the bottom part of the display.
The meter will read frequency of the ultrasonics up to about 150 kHz.
Above this range the meter is incapable of reading frequency due to
sampling rate. Power readings are still accurate as they are read in
a sampling mode over a time period built into the meter. To
read frequencies simply dial the meter to Hz.
Note: Probes are available in Quartz or Titanium in 18" or
with both Titanium and Quartz Probe; Titanium probe is 6" the
Quartx probe is 18". Both are available in either size.
