Toolkit Offers Vibration Analysis in Predictive Maintenance, Troubleshooting

Datastick Advanced Analysis and Reporting Toolkit--or DAART--PC software was introduced and demonstrated at the PdM Predictive Maintenance Technology Conference in Omaha, Nebraska, by Michael Scandling, Datastick Vice President of Marketing.

Datastick is known for its VSA-series line of handheld Vibration Spectrum Analyzers and software for the handheld and PC, which are used in conditions-based monitoring of rotating machinery for predictive maintenance and troubleshooting. The new DAART PC software imports measurement data that has been collected by VSAs or other data collectors that can provide csv-delimited, tab-delimited, or Excel files--and provides tools for analyzing those measurements, including some industry firsts.

Vibration analysts are now able to see impact pulses within bearing noise more clearly with the Datastick PulseDomain tool, which uses Datastick's new, refined demodulation technology. Datastick's new, exclusive Sharpener technology shows accurate frequency-domain information in any FFT, PulseDomain or Cepstrum graph.

Additional capabilities of DAART software include

  • the ability to import information from almost any bearing database, including one provided by Datastick
  • easily transform data back and forth between time-domain and velocity, displacement, or acceleration FFT waveforms
  • convert any waveform to a .WAV audio file so that analysts can listen to the sound of any bearing

In addition, two new metrics show high-energy areas of the spectrum superior to Crest Factor, the most commonly used tool for this purpose. Datastick Peaking shows the energy in the peak component of the vibration waveform, and Datastick Impact Factor shows periodic bursts of energy.
