Product Overview
The affordable high resolution vibration analysis tool for experts - that anyone can use!
Pocket VibrA Ultra offers incredibly high resolution frequency spectrum analysis (down to 0.02 Hz) allowing detailed analysis of bearing faults, gear meshing, vibration sideband frequencies etc.
Includes the ability to have user selected envelope demodulation filters, bearing database overlays on spectral plots etc.
Pocket VibrA Ultra also includes our world leading C-Trend PC software that allows automatic trending, report generation, emailing of alarms etc.
C-Trend is also a full asset management tool and can trend and monitor ANY process variable.
Specifications
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.

These 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.
