By accessing a spectrum on the Web Platform, the spectrum is shown for the active axes in terms of acceleration. The information is also available for the velocity and displacement quantities (see Metrics).
In addition, it is possible to access various analysis tools from the function table, highlighted in the image above.
Explained in more detail in the History of continuous data article.
It is possible to highlight specific frequencies, harmonics and sidebands on the graphs. Simply select the desired option, insert the frequency and click to apply. The points corresponding to the selected frequencies will be shown on the graph, as well as the window with the respective amplitudes.
It is possible to highlight the rotational frequency of the machine, as well as the frequencies of characteristic failure of the bearing for cases where it has been registered in the bearing database. The options are:
- RPM: Rotating frequency of machine;
- BPFI: Ball Pass Frequency of Inner ring;
- BPFO: Ball Pass Frequency of Outer ring;
- 2X BSF: Ball Spin Frequency;
- FTF: Fundamental Train Frequency.
Allows the spectrum quantity (acceleration, velocity or displacement) and the respective units to be changed.
Filters can be applied to help eliminate noise and highlight signal characteristics. By selecting this option, a new window will open where it is possible to choose the type of filter and the cutoff frequencies. The filter types are: High-pass, Low-pass and Band-pass.
Notes can be added for a determined frequency.
