1.3.2 Measurement with FastTracer
The FastTracer measurement device carries out a time-trend
analysis of x-y-z acceleration components detected in the
sensor application point of the sensor. The x-y-z reference
tern is the one indicated on the sensor casing and shall be
used to determine the direction of the measured accelerations.
Acquisition device or sensor
The device can acquire accelerations with maximum module corresponding to the full scale of your
FastTracer (± 18g, ± 5g, ± 2g) and frequency between 0 Hz and 2500 Hz. The FastTracer
acquisition sample rate is 18113.21 sample/s, i.e. 18113.21 acceleration measurements are
performed in the sensor positioning point in one second.
The signals acquired are digitally converted by a dedicated processor and digitally transmitted to the
Sequoia IT software installed on your computer (FTAnalyzer, Esplora 3D). Through mathematical
calculations, the software will provide all direct and indirect measurements needed for diagnostics
or experimental research.
1.3.3 Diagnostics and machine or structure characterization
With FastTracer you can analyse the machine vibrational signature to characterize structures or
monitoring of conditions.
Machine monitoring
With FastTracer you can carry out diagnostics for predictive maintenance according to two levels:
1.

st
level diagnosis: condition monitoring
The repeated measurement of the machine vibration acceleration RMS level in the
measurement point will identify the machine current operating condition and its progress
in time.
2.

nd
level diagnosis: cause inquiry
This level of inquiry is based on the FFT analysis of the acquired data and makes it
possible to identify the problem according to the spectrum shape. This type of diagnosis
is useful to identify faults such as rotor unbalancing, joint misalignment, damaged gears,
etc.
