Note
The appropriate alerts for a given machine will be a function of its design, service, and turning speed.
Utilizing the embedded PeakVue technology, the CSI 9420 identified developing problems
at a couple of test sites during early field trials. In both cases, the problem was not visible
with conventional low-frequency analysis. The following examples provide sample data
from one of the sites. Notice in the example that the velocity measurement is indicating
less than 0.1 in/s. The PeakVue trend, however, indicates high-frequency vibration that is
regularly in excess of 6 g's.
