Adash A4400 VA4 Pro 4-ch Vibration Analyzer + Recorder


Adash A4400 VA4 Pro Vibration Analyzer menu
Adash 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.

VA4Pro contains these measurement modes:
  • Recorder
  • Signal Analyser
  • Data Collector (Route measurements)
  • Run Up (Coast Down) measurements
  • Balancer
  • Signal Recorder
  • FASIT - NEW !!
  • Lubrication Control - NEW !!
  • Octave Analysis - NEW!!
Key features:
  • FASIT - Fault Source Identification Tools
  • FFT spectrum with 25 600 lines
  • 4 AC +  tacho + 4 DC channels (temp. pressure..)
  • Balancing Advisor helps you with balancing
Measurement of 4 channel simultaneously 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.

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.

FASIT - NEW !!
Adash VA4 Pro Vibration Analyzer FASIT

FASIT - Fault Source Idenification Tools


FASIT allows immediate accessment of the overall vibration severity according to ISO10816-3 and identification of the following faults using color scale:

- bearing fault
- unbalance
- misalignment
- looseness

FASIT is a handy tools even for experienced vibration analyst.

Example shown on the left indicates fault in the bearing; and also unbalance which usually happens in later stage of bearing fault.
     
Simultaneous Measurement
Adash VA4 Pro Vibration Analyzer / recorder

Multi-measurements can be measured in parallel for a single measurement point, that save time; and improve 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
  • Time signal (1k high pass filtered) for inspection of impacts due to bearing fault
  • FFT spectrum 0-20kHz, 25,600 lines 
  • Envelope Spectrum for bearing fault detection
  • label for bearing frequencies
     
Balancing
Adash VA4 Pro Vibration Analyzer - balancing

A4400 VA4Pro provides professional 2-plane balancing function.

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.








   
Data Collector
Adash A4400 VA4 Pro Vibration Analyzer - trend & compare

VA4Pro can be used as a Data Collector for routine data collection.

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 with time.

For experienced user, historical data can be downloaded for on-site trending and comparison, so that diagnosis can made on spot immediately.





     
Run-up / Coast Down
Adash A4400 VA4 Pro Vibration Analyzer waterfall

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)
  • Nyguist plot 
  • Waterfall plot (vs RPM or Time)
  • Cascade plot


     
Octave Analysis - NEW!
Adash A4400 VA4 Pro Vibration Analyzer - Octave Analysis

Octave Analysis


VA4Pro can provides 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.  

Octave 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.



   
NEW DDS2014 Monitoring Software
One software for all instruments!

The DDS2014 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 hierarchy 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 diagnosis.
