Product Overview

VibrA Ultra - Vibration Analyzer is the high end vibration analyser and CBM tool from C-Cubed.  Actually it is the combination of three tools:
                High specification vibration analyzer
                Two plane field balancer
                Machine and plant Inspection software

The VibrA Ultra - Vibration Analyser includes features such as 0.02 Hz resolution frequency resolution with a 51,000 line FFT, envelope demodulation and a bearing fault frequency database.   

The two plane field balancer is both powerful and simple to use with features such as expert trial wait location and live balance vectors making field balancing quicker and more accurate. 

Machine and plant inspections facilitate the user carrying out proactive maintenance as part of a CBM program. 

All the above features combine with C-Cubed's C-Trend software which allows the user to trend all data.  The ease of use and powerful features such as waterfall plots, auto emailing of alarms, bearing fault cursors and network connectivity make this the ideal solution for CBM programs.


Vibration Analyser

  • Fully waterproof and rugged ip67 construction
  • High resolution (0.3Hz) frequency spectra from 0Hz to 15kHz (and 0.02Hz from 0 to 1kHz)
  • Auto detects out of balance, misalignment, looseness etc
  • User selectable envelope demodulation filters
  • Analyzes bearing wear
  • Built-in IEPE (constant current) accelerometer power supply with BNC connector
  • Automatic RFID measurement point identification
  • Saves and reads measurement values to/from RFID tags (option)

  • Auto detection and trending of balance, misalignment, looseness etc
  • Easy to interpret colour graphic displays with predictive trendlines
  • Automatic reporting in MS Word
  • No software license fees and free updates


C-Trend Ultra software functionality:

Asset manager:

  • Displays asset status (OK, warning or critical) for ISO, bearing quality etc, with date and time of reading.
  • Assets can be easily Created, Edited, Deleted, Copied and Pasted into Sites.
  • Sites (and their assets) can be selectively downloaded to PocketVibrA unit.
  • Automatic set up and download of Routes.
  • Reports can be created on individual or groups of assets (selected via the Report Wizard) as editable Word files with embedded Excel graphs for trends and frequency plots.
  • Emails can be automatically generated on exceptions (alarms)

Measurement point display:

  • Total vibration (mm/s and g) from 0Hz to 15kHz, ISO (10Hz-1kHz), Bearing Quality (BDU), Crest factor, Demod (Envelope), VA Bands (instability, balance, misalignment and looseness) plus any number of user defined parameters (text or numerical values).
  • Individual readings (on any date) can be selected for frequency plot or time waveform display (all axes are zoomable).
  • Top ten peaks can be displayed and sorted by frequency or amplitude.
  • Fully adjustable harmonic cursors.
  • Zoomable "waterfall" diagrams with user selected data.

PocketVibrA Ultra software functionality:

Asset manager:

  • Displays sites, assets and measurement dates and times as a "tree" structure.
  • Stylus free navigation of route and measurement points and capture of readings using numeric keypad.
  • Auto identification of measurement points using RFID tags or auto recognition of “smart” accelerometer via easy to use set up procedure.
  • No set-up "meter mode" with full FFT and waveforms.

"Run asset" display:

  • Individual measurement points (MP) are numbered and described with text.
  • MPs colour coded to show if readings have been taken.
  • Previously taken readings can be viewed or retaken.
  • Readings can be saved to RFID tags for later recall and comparison with current readings.

Measurement point readings display:

  • User selectable, simultaneous display of any four from: ISO mm/s, Total RMS (mm/s or g), Bearing quality (BDU), Peak g, Crest Factor or Demod (Envelope).
  • Time waveform and frequency plots (fully zoomable) with fully adjustable harmonic cursors
  • VA bands display alarms as colour coded (red, amber, green) RMS values.

Vibra-Ultra-Vibration-Analyser-CBMThese are some typical screens that the user might see when using the unit. Extensive use is made of icons for function selection and both touch screen and keyboard entry are simultaneously available. Data is very easily entered by typically selecting from drop down menus. Zooming into displayed graphs etc is done simply by touching the screen and dragging a zoom box.
