Add digital HFD measurement to dBX
Many customers have had success with a combination of Envelope and HFD in analyzing bearing defects. Those that have used HFD would like to continue to do so with the dBX.

Thank you for your comment. The Microlog dBX does not support HFD measurements. This is because the Microlog dBX has 40 kHz frequency range. Previously Microlog CMXA series used to simulate HFD with a digital simulation called dHFD.
Your comment has been noted and a similar digital technique may be implemented in later software release.

We have had at least 7 customers ask about HFD with varying levels of concern when told that it is not currently available in the dBX
-
It would be nice to see the dBX have 8o kHz frequency range and have a system of HFD added or additionally something similar to Peakvue or Bentlys new variant of Peakdemod after all the world moves on and the latest and greatest from a supplier should reflect that.

Dear Microlog dBX user, thank you for your feedback.
The SKF Microlog dBX bandwidth is up to 40 kHz frequency range; thus, HFD is not supported.
Emerson's PeakVue, or Baker Hughes PeakDemod technology, can be used as an indicator of the overall asset health of rolling element bearings. We believe, as a bearing manufacturer with over 100 years of experience, that our SKF gE enveloping is superior in detecting bearing wear. Preventing unnecessary downtime.
Again, thank you for your feedback,

And for elements in the equipment other than REB's?

Dear SKF Microlog dBX user. Thank you for your feedback.
Have you tried using different SKF gE enveloping bands? SKF gE is configured with 4 bands, specifically for different bearing designs and applications. Band 4 can also be used to monitor wear, such as with gears. Band 3 is generally used to monitor REB bearings, while lower bands are more suited for sleeve bearings.
