VA4 Pro Analyzer / Recorder
VA4 Pro is
a professional and robust 4
channel Vibration Analyzer / Recorder, which is a valuable tools for
maiintenance engineer for fault diagnosis, balancing
and data collection / recording.
contains these measurement modes:
- Signal Analyser
- Data Collector
- Run Up (Coast Down)
- Signal Recorder
- FASIT - NEW
Control - NEW
Analysis - NEW!!
Measurement of 4
gives a lot of flexibility in
fault diagnosis. For instance, you can get a good insight of the
aligment by measuring the radial and axial vibration across the
coupling of the motor and pump.
- Fault Source Identification Tools
- FFT spectrum
- 4 AC
+ tacho + 4 DC
channels (temp. pressure..)
- Balancing Advisor helps
you with balancing
120Gb allows 35 hours
continous recording of 4
channel raw signals up to 25.6kHz. Even under pressure, you don't have
to worry that important data could be missed.
- Fault Source
allows immediate accessment of the overall vibration severity according
to ISO10816-3 and identification of the following faults
using color scale:
- bearing fault
FASIT is a handy tools even for experienced vibration analyst.
shown on the left indicates fault in the bearing; and also unbalance
which usually happens in later stage of bearing fault.
can be measured in parallel for
a single measurement point, that save time;
consistency in data especially when the machine speed or
running condition varies with time.
Example of multi-measurements:
- 10-1kHz Overall
Velocity according to ISO-2732
signal (1k high pass filtered) for inspection of
impacts due to bearing fault
spectrum 0-20kHz, 25,600
Spectrum for bearing fault detection
- label for bearing frequencies
provides professional 2-plane
The whole balancing process will be guided on
screen with easy-to-understand figures and instructions.
The weights will be automatically splitted and calculated for
situations where the location of weights is limited, e.g. fan.
VA4Pro can be used as a Data Collector for routine
Parallel Measurements are peformed
simultaneously, that save time in data collection
at each measurement point. It also improve consistency of data
especially when the speed or process condition of the machine varies
For experienced user, historical data can be downloaded for on-site
trending and comparison, so that diagnosis can made on spot
Run-up / Coast-down
or Vibration Time History
(overall & spectrum vs time) can be
easily carried out on A4400 VA4Pro. Raw time data can also be recorded
as a backup for critical machine. 4 DC Process Parameters can be
measured at the same
time for correlation analysis with vibration readings.
Differenet graph is available for run-up / coast-down analysis:
- Bode plot
(amplitude and phase vs rpm)
- Waterfall plot (vs
RPM or Time)
- Cascade plot
Octave Analysis (1/1, 1/3, 1/12 and 1/24 Oct) for sound and vibration
measurement. Human perception to noise is close to octave frequency
bands. Using the high resolution 1/24 octave analysis, more accurate
measurement can be made to determine the frequency of interest.
analysis can also be used for machine monitoring. Its high resolution
at low frequency can be used to identify the harmonics of rotating
speed; and the increase in vibration due to bearing or gearbox fault
can be seen at the high
frequency as well.
software for all instruments!
is the Adash software for managing your vibration
monitoring data professionally. Off-route and route data from VA4Pro
can be transferred to the SQL database; and stored in
tree structure, that allows you to trend the historical data, generate
alarm based on user-defined limits; and make comparison of spectra.
With the help of marker functions, characteristics frequencies of
bearing, gearbox, motor... can be identified easily for fault
