9.3) Waveform (linear and circular)
Updated at 3/7/2023
The waveform is the arrangement of the data coming from the DynaLoggers in graphical form in the time domain. It represents all possible variations in the set of values obtained in acceleration from the point where the sensor is installed, for the time the data set was acquired (by App or Gateway).
The waveform can be important for visualizing repeating patterns in the signal, such as beating or impacts, as well as modulations. The data can also be converted from acceleration to velocity and displacement.
To get to this screen see the section “Accessing the Vibration Spectral Screen”, which shows the various ways to view the waveform and spectra for each Spot. Below there is an example of a triaxial waveform obtained from a conveyor belt bearing.
In the same graph, instantaneous values, per axis, of: RMS, peak-to-peak, crest factor and kurtosis are available in the upper left corner. In addition, using the period cursors you can see the time difference between two distinct peaks, as well as the resulting frequency in Hz.
Circular waveform
The circular waveform is another way to analyze the same data, but plotted in polar coordinates.
To activate this form of visualization, simply, on the desired waveform, activate the “CIRCULAR” option at the top right of the screen.
One must also define the starting instant and the number of revolutions displayed on the graph.
For satisfactory results, it is recommended that the RPM of the location closest to the monitored point is correctly scaled. This can be changed momentarily at the top of the page for a real-time update of the waveform.
