Offline RPM Extraction Tool in Dewesoft
Hi all,
We are trying to extract RPM values from some data where in the test setup we were not able to place a tachometer/optical sensor.
As I understand Dewesoft does not have separate module for RPM Extraction so we do not have the flexibility to select (double, multiple) markers and let the algorithm extract the rpm in between easily as in LMS RPM Extraction add-in.
I found a Yotube Video showing manual RPM Extraction in Dewesoft but with the new Dewesoft versions we do not have the markers for time and frequency at the same time (see the attached picture) like we had in X3 we only have frequency markers.
Can you please let me know if there is a way to mark frequency and time of the points on Colormaps on a table (like old cursor table in X3) in the new version of Dewesoft?
My second question; are Dewesoft developers working on a RPM Extraction module for Dewesoft if not can you take this as a feature request, thanks.

Dear Matt,
if you are referring to the video, I would suggest using a Free marker on the FFT time waterfall.
The value can be displayed in a table and also copied to the clipboard and exported into Excel.
In the next version of Dewesoft (2021.6) we will release an option in Order tracking called Auto Tracker. This option will allow the user to extract the RPM signal from the vibration signal.
Best regards,
Hello Jernej,
Thanks for your detailed reply, the issue with the new marker table is it does not have the time data as in X3 cursor table and this makes manual tracking really time consuming, I was asking if the new marker table also shows the time data as in X3 (please see the picture below).
The Auto Tracker option sounds really nice, looking forward to use that once it is available (I hope Auto Tracker will have the flexibility to chose between single, double and multiple points as in LMS/HeadAcoustics Artemis), thanks.

Dear Matt,
new markers do not support yet the time information. The plan to support this is in 2022.
If by selecting multiple points, you mean that it should track multiple harmonics, then the answer is yes.
Best regards,
