Charting your results
Ultrasound will be produced differently for all types of systems. It may be strong on one side of
a bearing shaft, and weak on the other, depending upon the unique wear patterns. Therefore
it is very important to mark the test point, so that future readings can be taken from the exact
same position. Doing the same test with the sensitivity set differently can completely change
the results, therefore it is extremely important to keep track of the instruments settings for future
tests to be valid. These values can be entered into a computer spreadsheet program for creating
charts, and storing data.
Keep this information in your fi les, or tagged on the equipment itself. When returning to the same
equipment, perhaps several weeks or months later, you have the information you need to make a
decision as to the degree of wear in a particular piece of equipment.
It is worthwhile to show this information to supervisors and plant management. The problems you
identify and correct will eliminate costly downtime and energy loss, ultimately saving your Cor-
poration money. More scheduled repairs and less emergency work keeps your business under
control.
Vibration
Vibration, misalignment, or moving machinery which is not properly balanced can be deadly to
a system. These things can cause excessive wear bringing the life of any system to an early
demise.
All these problems have a common warning signal; increased ultrasonic energy. This ultrasonic
energy is generated from the friction associated with these problems, and can be detected with
the Tru Pointe
®
2100.
EXAMPLE: Maintaining a system using multiple pumps
or motors all of the same type. After testing a sample
of these bearings, the will be able to determine what
readings are normal or abnormal for each type.
REMINDER: To insure success, be consistent. If you
test a compressor bearing, for example, test the same
place, at the same sensitivity setting. It is a good idea
(although not necessary) to test units when they are
new, and keep your own records of what is acceptable
for a new piece of equipment.
See the previous section on charting your results.
WARNING! Be careful when working around rotating
machinery. The headphones will dampen much of the
sound around you. Use care, and be alert at all times.
Make certain the headphone cord is away from moving
machine parts.
