Reminder:
To insure success
be consistent
... If you test compressor mounts,
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.
You may want to show your customers the measures you take to insure an
accurate indication of the health of their system. The customer should also be
happy to know that this test will show the early warning signs of system failure.
See the previous page on charting your results.
WARNING
Be careful when working around rotating machinery. The headphones will dampen much
of the sound which may cause you to forget that the machine is moving. Use care,
common sense, and be alert at all times. Make certain the cord from the headphones is
out of the way of any moving machine member.
Other Applications
Use your imagination
. The AccuTrak
®
is probably one of the most versatile test
instruments you can own. Keep in mind that ultrasonic sound is generally
produced by
F
riction,
A
rcing, and
T
urbulence (F A T). Therefore any pressurized
gas, moving machine, or electrical system can be tested.
Electrical Arcing
A jump in electrical current or Arc will make a popping, frying, or buzzing noise in
the ultrasonic range. The AccuTrak
®
can be used to locate electrical failures
which are causing a decline in power quality. Use to test circuit breakers, buss
bars, relays, corrosion in contacts, or poor insulation.
Warning
Be careful, and use common sense around electrical currents. Keep in
mind the nose of the AccuTrak
®
is metal, use the plastic waveguide, and
keep at a safe distance!
Fan Belts
You may be familiar with the sound of a loose fan belt in a car. Early warning of
such wear is indicated by a similar sound in the ultrasonic range.
