VIBex
State-of-the-art vibrations monitoring system
VIBex (vibrations monitoring system) - Description
VIBex is the state-of-the-art system dedicated for vibration monitoring and diagnostics of rotating machinery, especially with rolling bearings, featuring:
Automated configuration of the system.
Automated calculation of machine characteristic frequencies.
Automatic setting of alarm limits.
Fast preparation of configuaration reports.
Quick diagnostic of rolling bearings, based on the method of enveloping.
Clear and comprehensive guiding to the cause of the problem.
Storage of machines history of operation in the high perfomance database.
Notification about detected linit violations via e-mail (also on dial-up connections). Optimized remote access to the system.
Vibex under PC
VIBex runs on PC under Windows 2000 or Windows XP Professional Edition. VIBDIN modules are used as data aquisition modules. The server is the industrial PC computer. It is possible to access the data in the server remotely.
The system can acquire data from vibration sensors: accelerometers (ICP ® type) or relative vibration sensors (eddycurrent) as well as other sensors, which are used as operational
parameters (e.g. power, rotational speed, temeratures ...).
The system is installed on a machine with little effort. After sensors are connected to the VIBdin module and it is connected to the VIBex server, you can start configuration. The system
is configured with easy-to-use graphical tool. After you setup input channels, you define mechanical features of your machine. The system automatically calculates speeds of shafts and
characteristic frequencies of the machine.
Next, when you assign sensors to machine components, VIBex automatically creates all numerical algorthms to monitor your machine. Applied algorithm range from basic overview of technical state, to advanced ones, like harmonics. Rolling bearings are monitored with the method of enveloping, which can detect symptoms of their wear much earlier than just looking to the spectrum.
VIBex automatically creates limits for all calculated values, what saves hours of configuration work. The system also containes the tool for automatic calculation of values of limit (alerts and alarms), what will save you even more hours of configuration work.
After the system is setup and running, you can watch your machine in a variety of simple-to-use, but full-featured set of plots. You see the status of a problem (if there is one) just in one mouse click. Any detected alarm is presented in the tree view on the left and is propagated up, so that you can easily get to the source.
Variety of plots
VIBex provides a variety of plots like:
• mimic screen shows diagram of the machine with values of chosen channels, like rms or any other value available in the system; the user can build its own sceens with the
garaphical tool.
• data table shows current values from chosen channels
• data table shows events from given period, type, source etc.
• waveform shows original waveform or its envelope; it is possible to play it as a sound or export to an external
software as .wav or .csv file
• spectrum can be shown as normal or order spectrum in both frequency or order domain
• trend shows several channels on the plot; data can be filtered, so that only
• data from one state is presented
The VIBex system is very user-friendly. You can open plots with just one mouse click, you can jump between different plots, or export them to your report (into MSWord or as a picture file).
When you investigate spectrum of vibration signal you can easily add the reference spectrum (stored in known, good conditions), you can change unit, spectrum type or just colors.
You can also add harmonic lines of chosen mechanical components.
You can even identify potential cause of a chosen spectral line. This adds new dimension to the laborious work of the engineer evaluating the data.
There are much more functions in the system, all giving you advanced, but easy to use tool to monitor your machinery.
