The last function is particularly useful for condition monitoring: comparing measures taken on the
same machine at different times can help define the machine operating condition. Of course, the
analysed event must be the same and measurements shall be taken by positioning the sensor in the
same point at all times. This way it is possible to provide a time-trend analysis of the machine
general conditions and determine its operating state. Sections [1] and [2] provide indications on the
events to be analysed and the sensor positioning for the machine condition monitoring.
As already said, FTAnalyzer can also process filed measures recorded before processing. The data
files are viewed by FTAnalyzer as virtual devices called File Devices.
FTAnalyzer enables to analyse the acquisition device measures in time domain, frequency domain
or both. In time domain you can view the acceleration components in the measurement point or
indirect measures resulting from processing, such as Rms values or xy, xz, yz and xyz modules.

FTAnalyzer: measurements and diagnostics
In the frequency domain you can view the acceleration,
speed or displacement component spectrum in the sensor
application point through the FTT analysis. The Triggered
display mode is particularly useful in this respect as it
makes it possible to synchronize data acquisition with
vibrational events whose characteristics have been
specified by the user for an established time. FTAnalyzer
functions enable skilled users to study vibrational
phenomena,
to
understand
cause-fault
relations
(forthcoming fault, part slackening, etc.) and the resulting
effect on the machine vibrational signature or other
parameters (e.g. high Rms values, abnormal widths, etc.).
