To avoid over lubrication:
1. Don‘t lubricate if the base line reading and base line sound quality is maintained.
2. When lubricating, use just enough lubricant to bring the ultrasonic reading to baseline.
3. As mentioned above, use caution. Some lubricants will need time to uniformly cover the bear-
ing surfaces.

Slow speed bearings
Monitoring slow speed bearings is possible with the Ultraprobe 10000. Due to the sensitivity range and
the frequency tuning, it is quite possible to listen to the acoustic quality of bearings. In extremely slow
bearings (less 25 RPM), it is often necessary to disregard the display and listen to the sound of the bear-
ing. In these extreme situations, the bearings are usually large (1/2“ and up) and greased with high vis-
cosity lubricant. Most often no sound will be heard as the grease will absorb most of the acoustic energy.
If a sound is heard, usually a crackling sound, there is some indication of deformity occurring. On most
other slow speed bearings, it is possible to set a base line and monitor as described.
FFT Interface
The Ultraprobe may be interfaced with FFT‘s via the UE-MP-BNC-2 Miniphone to BNC connector or the
UE DC2 FFT Adapter. The Miniphone plug is inserted into the headphone jack of the Ultraprobe and the
BNC connector is attached to the analog-in connector of the FFT. There are also two accessories that
connect to an FFT via the Ultraprobe I/O port. They are the 5PC MP (using a Miniphone connector to the
FFT) and the 5PC-BNC (using a BNC connector to the FFT). These connectors enable an FFT to re-
ceive the heterodyned, (translated) low frequency sound information detected from the Ultraprobe. In this
instance it can be used to monitor and trend bearings, including low speed bearings. It can also extend
the use of the FFT to record all types mechanical information such as leaking valves, cavitation, gear
wear, etc.
General mechanical trouble shooting
As operating equipment begins to fail due to component wear, breakage or misalignment , sonic and
more importantly, ultrasonic shifts occur. The accompanying mound pattern changes can save time and
guess work in diagnosing problems if they are adequately monitored. Therefore, an ultrasonic history of
key components can prevent unplanned downtime. And just as important, if equipment should begin to
fail in the field, the ULTRAPROBE can be extremely useful in trouble shooting
problems.
