Set up efficient data collection as follows:
•
Use/create a well-formed network which conforms to best practices as described
in the WirelessHART System Engineering Guide.
•
Collect an averaged spectrum for overall vibration (recommended). Do not
collect the waveform used to calculate the overall vibration value in the device
itself. Starting in AMS Machinery Manager v5.61, the spectrum can be 400 lines
instead of 800 lines, which further increases the availability of bandwidth. If you
require the waveform from overall vibration, you can collect it on demand.
•
For PeakVue, collect the waveform; the spectrum is always collected with the
waveform. You need the waveform in order to use Auto-correlation to look for
periodicity in the waveform. Auto-correlation helps you distinguish between
impacting that is the result of under-lubrication or pump cavitation versus actual
bearing damage.
