lines). Each bin contains a percentage of the RPM range. The
user may determine the actual RPM range contained in each bin
by dividing the spectrum range (in RPM) by the number of bins.
The Vibrex unit uses a 400-bin FFT setup. If the frequency range
selected is 0 to 24,000 RPM, each bin consists of 60 RPM worth
of vibration energy. As the RPM range goes down, the bins hold
fewer RPM, so the RPM accuracy is generally improved for the
spectrum. When the user prints raw FFT data, both the header
information containing the annotation, channels numbers, RPM
range, day/date code, and so on are recorded with the vibration
energy in each bin.
The number in each line of the FFT as printed in the Terminal or
Hyperterminal program is equal to the inches per second (IPS)
divided by 1000. For example, if the range selected was 24,000
RPM, the 9
correspond to 540 RPM in the spectra and the 200
would correspond to 12,000 RPM.
The value in storing the vibration measurements as FFT data lies
in its PC versatility. The user can create plots and graphs of the
data, using the Honeywell V2K Plot Software program. For
details on how to use this program to plot FFT data, see the V2K
Plot Software User Guide.
