Dear Colleagues,

Two large Industrial Sites have their readily implemented data logging system that records and stores waveforms from 2-axis accelerometers in WAV stereo files (non-compressed). Approx. 300+100 accelerometers are solid-mounted on machines and *.WAV loggers are installed next to the sensors. The system is built by their own, for own use, but of good performances: 0-24 kHz bandwidth, 10 mG resolution. Those 400 accelerometers produce ~1200 of 20-second waveforms daily and store them for up to ~6 months totalling to ~800 Gb by the end of control period. Not bad. They wants us as little as to watch the trends.

Does anybody know serious vibration analysis software that can read WAV stereo files? Please advise. Many thanks.

I'm pretty sure VSI Rotate will.

Adash DDS software can import a wave file as a time signal into its database. Once there, you can convert the time signal into a spectrum and store that as a separate data cell.
It will be a tad tedious to do that with 1200 waveforms by hand, but I am sure if you ask them they can come up with an automated solution.
Beat Regards,
Tom Murphy

Thank you very much, Patrick and Tom! SUrprisively, could not allocate either Vold Solutions, Inc. for VSI Rotate (no website found) or ADASH for their DDS (their both webs look dead).

Furthemore, have not found a vendor for any of them! If you have any relevant contact details or know where to download their trials, please advise.

Thanks alot!

Bob

Last time I checked, this company owned VSI Rotate

Bob, You might try this link as well.

The system will record airborne as well as contact probe information and translate it to a true RMS time wave form. It should be able to do what you need when importing the .wav file. The “correctness” of the amplitudes may not match the amplitude or frequency response of an accelerometer, but if starting with a base line and trending, the same rules apply. The company is very willing to work with a client so you might be able to license the software only. I am an end user and have been very satisfied with the entire package.

Thank you for a good link. Spoke to them today. Their system would not read 2-axis accelerometer, but they use a very interesting concept of a palmtop data collector. Also their ultrasound technique is a good supplementary tool.

Dropped email to ADASH -- no reply yet.

Talking to ATA Eng. on their RotatePLUS.

Maybe somebody knows other Software to read WAV stereo files?

VibGraph Expert from 01db can read the WAV file. Pls email me direct at afmn55@streamyx.com and I will send you the details
