Pocket VibrA PRO

Pocket VibrA PRO is a full featured hand held portable vibration analyser designed specifically to deliver ease of use and practicality for the maintenance environment. It fulfills two powerful functions as both an "Expert Vibration Meter" providing instant diagnostic information, as well as a complete vibration analysis system ready to very easily set up an effective condition monitoring program with the minimum of fuss.

The simplicity of using the VibrA PRO hand held vibration analyser is unique in the vibration analysis industry, and allows users to measure and analyse machine vibration results with minimal training.

VibrA PRO reports overall vibration levels against the ISO standards and measures bearing damage in custom BDU units. In addition, instant diagnostic vibration results are available with a RED, YELLOW, GREEN health-check based on four preset vibration analysis diagnostic ranges that indicate Instability, Unbalance, Misalignment and Looseness, to assist maintenance technicians with rapid equipment troubleshooting. Detailed FFT and Time Waverform data is also instantly available for the more experienced user.

Pocket VibrA PRO is also a powerful, full featured vibration analysis system with a simple, highly intuitive interface, suitable for easily setting up and managing a conditon monitoring or predictive maintenance program in any plant. High resolution FFT and Time Waveform graphics are provided with a touch activated zoom function. Bearing condition is reported in Bearing Damage Units (BDU's) and four customisable measurement ranges allow for user defined warning and alarm levels to be set by an advanced user in user-defined frequency ranges.

Included with the VibrA PRO system is the comprehensive C-TREND windows based route management and data analysis PC software. This allows assets and data collection routes to be set up off-line then synchronised with the portable vibration analsysis unit. Recorded vibration data is uploaded to C-Trend after collection for an instant summary of alarm levels throughuot the plant that may be clicked through for detailed FFT, TIME Waveform and multi-range TREND analysis of each machine. The programs report wizard may be used to generate editable detailed analytical reports in Microsoft WORD format.

The POCKET VibrA hand held portable vibration anaylser from C³ is available as hand held stand-alone systems or fully integrated with the Stealth laser alignment kit, using the Stealth system's advanced handheld PDA control unit.

The Pocket VibrA PRO system provides a simple representation of vibration data with clear, straight-forward vibration diagnostic results that do not require the user to have high level vibration training.

VibrA PRO makes condition monitory both reasonably affordable and accessible without detailed vibration training. It is a vibration analyser that is highly suited to the needs of the maintenance industry, with features to suit a range of applications from fast, simple vibration spot checks to assisted diagnostics and detailed expert level vibration analysis and trend monitoring.

Advanced features of the Pocket VibrA PRO

Detailed Features

C-Trend Software Functionality:

Asset manager:

• Displays asset status (valid, warning or alarm) for ISO mm/s and bearing quality with date and time of reading.
• Assets can be Created, Edited, Deleted, Copied and Pasted into Sites.
• Sites (and their assets) can be selectively added to a sync list for downloading to PocketVibrA unit.
• Routes can be automatically set up and down loaded.
• Reports can be created on indiv idual or groups of assets (selected via the Report Wizard) and produce editable Word files with embedded Excel graphs for trends and frequency plots.

Measurement point display:

• Total vibration (mm/s and g), ISO mm/s (10Hz-1kHz), Bearing Quality, VA Bands (instability, balance, misalignment and looseness) plus any number of user defined parameters (text or numerical v alues).
• Individual readings (on any date) can be selected f or frequency plot or wav eform display (all axes are zoomable). Top ten peaks can be displayed and sorted by frequency or amplitude.

PocketVibrA Software Functionality:

• 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 key pad.
• Assets can be Created, Edited, Copied and Pasted into Sites (password protected on Pocket VibrA).
• Single and continuous reading "meter" mode with continuous FFT display.
• Options to “"un asset" (take new readings) or "continue asset" (add to previous readings).
• Auto identification of measurement points using   barcodes or auto recognition of "smart" accelerometer via easy to use set up procedure.

•   Individual vibration measurement points (MP) are numbered and described with text.
• MPs are colour coded to show if a reading has been taken (red) or not yet taken (green).
• Previously taken vibration readings can be viewed or retaken.

•   User selectable simultaneous display of any four from: ISO mm/s, Total RMS (mm/s or g), Bearing quality, Peak (mm/s or g) or Crest Factor.
• Time waveform and frequency plots (zoomable axes).
• VA bands display as alarm colour coded RMS values.
