Electrical Inspection: Arcing,
Tracking & Corona
-
Arcing, tracking, & corona discharge
produce ultrasound at the site of emission. These electrical discharges can be located quickly
by scanning an area with Ultraprobe. The signal is heard as a frying
or buzzing sound in the headset. As with pressure or vacuum leak detection, the closer the instrument
is to the discharge, the more intense the signal. Test: switchgear, transformers, circuit breakers, buss
bars, relays, junction boxes, insulators, and other electrical gear.

Bearing Inspection & Monitoring
-
Ultraprobe detects the earliest stage of bearing failure. NASA research
has demonstrated that ultrasound bearing monitoring will locate potential bearing failure long before
it is detected by traditional heat and vibration methods. With the
Ultraprobe, users hear the sound quality of a bearing as well as monitor
amplitude changes on the display/meter. This provides the ability to trend, trouble shoot and confirm
potential bearing problems.

Steam Trap Inspection
-
Major steam trap manufacturers have recommended ultrasound
inspection of steam traps as one of the most reliable methods available.
By converting the ultrasonic elements of a working steam trap into the audible range, Ultraprobe
allows users to hear through headphones and see on a display/meter the exact condition of a
steam trap while it is on line. Blow-by, machine gunning, oversized traps or line blockage are all
easily detected. Frequency tuning enhances Ultraprobe’s ability to
discriminate between condensate and steam.

Pressure/Vacuum Leaks
-
As any gas (air, oxygen, nitrogen, etc.) passes through a leak orifice,
it generates a turbulent flow with detectable high frequency components.
By scanning the test area with an Ultraprobe, a leak can be heard through the headset as a
rushing sound or noted on the display/meter. The closer the instrument
is to the leak, the louder the rushing sound and the higher the reading.

range.
het·er·o·dyne adj. - Having alternating currents of two different frequencies that are combined to produce two new frequencies, the sum and difference of the original frequencies, either of which may be used in radio or television receivers by proper tuning or filtering.
tr.v. het·er·o·dyned, het·er·o·dyn·ing, het·er·o·dynes - To combine (a radio-frequency wave) with a locally generated wave of different frequency in order to produce a new frequency equal to the sum or difference of the two.
