adjustment to eliminate any extraneous pipe noise and you will be able to hear only the internal
fl ow of the valve.
By using the readings on the display and your ear, you can determine which side of the valve is
leaking.
Bearings and Moving Machinery
The most common mechanical failure is a broken or seized bearing. However this type of failure
normally does not happen instantly. When the bearing begins to fail, the sound that it makes
changes. These changes occur in the ultrasonic range and can be detected with the Tru Pointe
®
2100 by touching the bearing housing with the touch probe and listening for abnormal sounds.
Periodic preventive maintenance tests can prevent major disasters in both the machinery and
down time.
Bearings... The First Test
The fi rst test is very important. This is the reading that all future tests will be based on.
With some experience you will be able to compare two similar bearings and identify the sound
of a good bearing from a worn one just by using your ear. When time passes between tests,
however, it is very important to log your results because the slope of the curve that you will
generate will predict the future failure of the bearing.
To take a reading on a mechanical system, such as a bearing or gear box, you must use the
touch probe attachment. Touch the end of the probe to the outer housing of the gear box or
bearing, making a good contact. Do not press very hard at any given point when collecting data.
Use just enough force to keep the tip of the probe in place, and try to be consistent with the
amount of pressure you use. It is often effective to use only the weight of the Tru Pointe

itself to hold the tip in place.
Adjust the sensitivity so that the intensity meter reads 5-6 LEDs. This gives you room on the
display for future readings.
As the bearing wears the ultrasonic sound intensity will increase. Future readings can indicate
the extent of this wear.
When testing a bearing or other moving machinery it is important to:
1. Record your volume, sensitivity, and frequency range.
2. Record the level on the alphanumeric display.
3. Record or mark the test point where the level was taken.
4. Record the temperature using a thermometer
By recording this Data you have the most accurate and repeatable test possible. Although the
sound of a moving machine member may
fl uctuate, the Tru Pointe
®
2100’s built in peak hold
feature will allow you to assign a number to the sound level emanating from the item being tested.
Use this number to compare future tests.
