Dear All, It was very nice reading replies to this subject over the past 3 years.I dont know if much of ur opinions have changed so far. I wonderd about DLI prouducts not being of so much interest in the disscution.I belive the Expert alert soft ware is a very powerfull tool in the OEM world.It saves you very much of ur valuable time by making the analysis simple. I would like to read on ur comments on this. B/R
best regards

And therein lies the problem.... as discussions on this board illustrate, many vibration problems are not at all "simple" even though we'd like them to be. Many "systems" that try to make complex issues "simple" just don't work, because it's just not possible.

I have seen the DLI in operation and was amazed how well it performed and did its diagnostics and basically as far as PdM goes - it really did a good job on all observed. I was impressed. Remember; we're doing PdM for the most part and not vibration analyses trouble-shooting complex problems. There is a difference and should be a seperation I think.
Cordially,
Sam

Good point, Sam. I suppose we should work at making "detection" via PdM as easy as possible, which would allow more time to do the requisite "diagnostics".

Rusty

As I understand it, the Commtest cannot collect route data in 2 channels simultaneously. Am I mistaken, because that is one of the CSI tools like Rusty described that is a real timesaver that can greatly increase efficiency?
I also seem to remember from the demo that there were a few higher end diagnostics in the 2120-2 and Consultant that the VB3000 couldn't do.
I really liked the software, price and support from Commtest, though.
The new Commtest vb7s do allow for simultaneous data collection on 2 channels. I was a Beta tester for these units and while the speed of a 2120 or 2130 per bearing is not as fast, they are solid data collectors. The technical support Commtest provides is great. They are kind of cumbersome when doing extra analysis in that you have to push a couple more buttons but the analysis parameters are plentiful. The analysis software is much more functional than RBMware in that it is a true Windows program...plus the are a lot cheaper than CSI. |

Does that mean Commtest, Pruftechnik, SKF et al are taking us for a ride? Is there any sense in buying those at all then?
SKF's Microlog is an emulated 2 channel.

But; PdM route collection - DLI does 3 ch or will do a triax all at once.
