Recording
Ultrasound Files for AVM Ultranalysis |
Allan Rienstra,
Editor
The Ultrawave Technology Report |
|
So many
ultrasound users ask us how to record ultrasound
signals captured by their detector. The high
sensitivity of ultrasound detectors coupled with
their ability to filter out ambient plant noise
makes them the ideal instrument for trouble shooting
electrical systems and rotating machinery.
Ultrasound is such a great asset to your existing
inspections and really helps you reinforce your
infrared and vibration programs. In addition to
listening and recording ultrasound decibel levels,
inspectors are recording ultrasound signals for
library building, sharing, consulting, and analysis.
Our
concern at SDT is that the data being recorded is
useful. That means educating end users on the
different media and file formats available for
making and savings their recordings. You can choose
to make your recordings with magnetic tape, digital
voice recorders, and direct to your vibration data
collectors. The sample rates you establish for your
recordings will either enhance or diminish the
quality and usefulness of your file. We ask, "why do
you want to record ultrasound files?" Are you
building a library for training new inspectors and
sharing experiences with colleagues? Or are you
recording a sound file on a slow speed bearing for
analysis in
time waveform and spectrum analysis software?
Whatever your reason for recording ultrasound files
from your detector, SDT is committed to helping you
do it the right way. We've added several new pages
to our website to help educate you about this topic.
We've also created a short
Power Point Presentation that discusses choosing
the right recording method for AVM Ultranalysis.
Please call or email us with your questions on this

Files - Choosing the Right Recording Method for AVM Ultranalysis |

Capturing
sound files from an ultrasonic detector such as the
SDT170 (or any other detector) is as simple as
connecting a good quality digital recording device to
the headphone output and following some simple
guidelines for collecting the signal.
We've put
together a short presentation that addresses the do's
and don'ts for recording ultrasound files. You can
download the presentation by

the file is large at 16MB.

Acoustic
Vibration Monitoring for Conditioned Based Lubrication,
by Paul Klimuc, SDT
Session Date: Tuesday September 16 (4:00 - 4:45PM)
Condition Based
vs. Time Based Lubrication of Bearings
Bearings
lubricated on a time based schedule are more prone to
premature failure than bearings that follow a condition
based schedule. In a time-based scenario lubricant is
rarely added at the exact time it is needed; allowing
the bearing to run "dry" for extended time frames. When
the bearing is finally greased the amount of lubrication
can be too little or too much. In either case the
implications for bearing life are negative.
A condition based
schedule involves frequently monitoring the bearing to
establish normal baseline friction levels. As the job of
lubricant is to reduce friction, it stands to reason
that increased baseline readings would indicate a need
for re-lubrication. Monitoring friction levels while
lubricating serves as a guide to prevent over
lubrication.
A simple and
common approach to monitoring and setting baseline
friction levels is with an ultrasonic data collector.
These portable instruments use high frequency
piezoelectric sensors to detect, measure, and trend
ultrasonic signals from rotating equipment. Friction
from the bearing excites the sensor which in turn
produces a micro volt charge which is accurately
measured and referenced to a decibel log scale. This
data is displayed onscreen and stored to the internal
data collector. It can then be transferred to PC where
for further analysis. As a rule any bearing with a
measured ultrasound value 8-10 dBµV over its baseline
should be greased using the acoustic lube method.

As
predictive maintenance professionals, determining the
condition of our production machinery means interpreting
data from various sources including vibration analysis,
balancing reports, thermography scans, and oil analysis
lab results. The latest discipline for predictive
maintenance technicians involves analyzing ultrasound
signals captured from their ultrasound inspection meter.
By looking at ultrasound files in the time and frequency
domain a lot can be learned, and confirmed, about the
health of machines.
