Foreword
Congratulations! And thank you for selecting the VIBXPERT II
FFT data collector and signal analyzer*. This newly developed
measurement device is not just the ideal companion for your routine
measurement round, but also a reliable on-site aid for recording and
analyzing complex machine signals.
VIBXPERT records all types of machine vibrations, bearing
conditions as well as process and visual inspection data, and
transfers this information to the OMNITREND maintenance software
for evaluation, archiving and documentation.
The combination of its extensive range of features and easy
operation makes VIBXPERT the effective choice for a wide range of
applications:
• High measurement accuracy and high-speed data collection
• Operating modes:
'Route' for routine data collection for condition-based
maintenance,
'Multimode' for individual measurements for machine diagnosis
'Balancing' in one or two planes (optional).
'Machine templates' for recurrent measurement tasks within the
scope of acceptance or service measurements
• Almost every type of sensor can be connected
• One or two measurement channels (analog);
Upgrade to 2-channel device at any time via password.
Hardware
• Two synchronous measurement channels for diagnosis of
complex measurements (e.g. shaft vibration).
• Sufficient storage capacity (2 GB CompactFlash).
• Dustproof and splashproof (IP65) - ideal for use in demanding
industrial environments
• Connector technology compatible to VIBSCANNER (same cable)
• Connector for NiCrNi thermocouples
• Connector for headphones
Data collection and data analysis
• Overall values
- Vibration acceleration, velocity, displacement
- Current & voltage (process parameters)
- Shock pulse (bearing condition)
- Temperature
- RPM
• Signals
- Frequency-based and order-based data collection
- Amplitude, envelope, order spectra
- Cepstrum
- Time waveform
- Phase measurement (synchronous, cross channel)
- Dynamic shaft movement (Orbit and shaft displacement)
Foreword
* Also referred to as 'VIBXPERT' and
'device' in these operating instructions.

Foreword
Structural analysis:
- Coast down / Run up analysis (natural frequencies, machine)
- Impact test (natural frequencies, machine components)
• Advanced measurements
- 1+1 dual measurement (simultaneous 2-channel measurement)
- Multitask (measure multiple measurement tasks in a sequence)
- On-site balancing in one or two planes
- TrendingSpectrum (a measurement provides a time signal, a
spectrum and several characteristic overall values, in route and
template mode).
- Recording
- Multiplexer measurements: Data collection via VIBRONET field
multiplexer
Ergonomics
• Large, backlit color display* ensures clear data presentation and
optimum readability
• Easy-to-use keypad
• Three alarm LEDs (red-yellow-green) indicate if thresholds have
been exceeded (based on ISO standards). A blue LED lights up if
everything is OK.
• Daylight sensor controls keyboard illumination
• Graphical user interface
• Color-coded connectors
• Online, context-sensitive HELP
Power supply
• Lithium-Ion battery of latest generation for more than 8 hours of
operation
• Smart battery charging in VIBXPERT
• Automatic power management (display, device)
Communication
• Fully networkable
• PC connection via USB, Ethernet, RS232.
Documentation
• Printing out of reports, directly on paper or as a PDF file.
VIBXPERT* from PRÜFTECHNIK once again demonstrates
the company's skills and innovative strength in the field of
maintenance, and is a consistent advancement in the series
of successful portable device systems such as VIBSCANNER,
VIBROCORD, VIBROTIP, VIBCODE.
Also, we would like to make you aware of the application-oriented
seminars offered by PRÜFTECHNIK that feature a significant practical
segment. They are very well received by course participants and
you will find them to be a good investment.
