Striving for continuous improvements to the analysis tools and facilitate the use of our platform, Dynamox has just launched a series of new updates. Check them out below!
1) Spectral trend
The user is now able to monitor the trends of data collected by spectra. This new tool is available by clicking the "TREND" button on the top right corner of the Spot Viewer screen.
By clicking this button, the user will be taken to the "Spectral Trend" screen, and will find by default the overall RMS trends for acceleration, velocity and displacement. With this tool it will be possible to view the history of spectral measurements in a very visual way, thus showing possible evolutions in vibration levels.
To further diversify trend analyses, we offer more than 80 different types of graphs, via the "GRAPHS" button in the top right corner. The available graphs show global metrics, by frequency range and many more. In addition, multiple graphs can be added side by side to compare the data trends.
This tool can assist in the analysis and detection of failures, as it allows the user to select metrics by frequency bands, which in turn can highlight developments in the vibration pattern of different machine components.
2) Asset frequency markers for spectra
This new tool on the Web Platform allows the insertion of frequency markers to be viewed on the spectral graphs.
To perform this action, access the configurations of the desired machine via the asset tree. On the "Frequencies" tab, the user can insert a new marker by clicking the "+ Frequency" button. Information includes the marker name, unit, frequency in which it appears, bandwidth, number of harmonics and color to be used.
When analyzing a spectrum, the marker will be available together with the other tools, by clicking on the wave symbol. When the marker is activated, indicative lines will appear on the spectrum according to the configuration made previously.
This tool helps users to visually identify the frequency of interest and its harmonics. It can be useful for marking gear frequencies, modulations and many more.
3) Configure hardware (LED) alerts on the Web Platform
Previously, it was only possible to configure hardware alerts via the mobile app, but now they can also be done on the Web Platform. This new feature allows analysts, who may be far away from the sensors, to edit the LED alert limits of the DynaLoggers.
On the Web Platform, the hardware alerts are located together with the software alerts, in the spot editor.
Note: any operation performed will be transferred to the sensor during the next data collection (via app or gateway).
4) Compare vibration spectra on the Web Platform
It is now possible to view two vibration spectra side by side, enabling the comparison of spectra collected at any moment in time and also between different spots. This option is available once the user has selected a spectrum via the "COMPARE" button located in the top right corner of the screen.
By clicking this button, a window will open showing which spectra are available for comparison. To select a spectrum, click the "+" button to the side of the spectrum and confirm the selection by clicking "SELECT". To find the desired spectrum with greater ease, the user can search by machine name, spot or dyid and also refine the search by date at the top of the screen.
This tool is designed to help analysts when diagnosing failures, since the analyst can compare vibration spectra side by side from different collection dates and examine the evolution of vibration amplitudes or even the appearance of new failure frequencies of the spot. Besides this, all of the analysis tools are available to carry out a detailed analysis of each spectrum.
5) Time reference in the Spot Viewer
The Web Platform has another new tool for analyzing data. Via the Spot Viewer, it is possible for the user to select a period of continuous collections as a reference for future analyses. For example, after implementing a maintenance action and knowing that the machine is functioning well, the post-implementation period could be used as a time reference. This way, at any moment in the future, the reference can be accessed in order to make a comparison with the current vibration and temperature data.
To configure the time reference, click on the option "REFERENCE", taking care to choose the correct time period from the start date to the end date.
The reference can be viewed at any time by clicking on the clock button to the side of the date options and selecting "View Reference".
This tool can be used in conjunction with the comparison tool on the Spot Viewer to enable the comparison of overall continuous data side by side.
To do this, a time period must first be defined as a reference, as explained above. Then, click on the "COMPARE" option and select the same spot. The two will appear side by side, so one side can be chosen as the reference by selecting "View Reference" and the other side will free to view the data from any time period (select the period from the calender symbol).
This side by side view with the "View Reference" option allows the comparison of data from any moment in the history of the spot with the reference period (of the same spot), helping to identify atypical vibrational behavior.
6) Search by dyid on the list of spots associated to a gateway
The serial number, or dyid, of a DynaLogger can now be used as a search option in order to identify a spot from the list of spots associated to a gateway. This option aims to improve the usability of this screen.
