Hello to All

Question: is anybody out there using C.S.I.'s 643tx accell for taking route data. I would like to hear opinions regarding the performance of these units. Do you think they are worth using for route collection? The thing that caught my eye was the time factor reduction. three points with one click.They say they are very good in the primary direction and this is where I start to wonder.What about the secondary directions? They seem to shy away a little on this subject. If you are using one do you see much difference from using one accel and moving from point to point.I do like the pad for mounting no second guessing about rail direction from one collection to the next always the same you could be 180 degrees different I suppose. I just like anything that woiuld give me a leg up on cutting down collection time in any respect looking forward to hearing you thoughts and suggestions.

If you use the search feature on this site, you will find we have discussed this before.

Someone can correct me: I didn't think CSI manufactured accels?????

Doing 3 channels at once requires a 3 channel box capable of processing 3 channels at once; add a fourth for phase!

Time gained, quality lost!? Three reading, one position? Above the split, below the split, direction of rotation - all are necessary IMHO.

I'm going to assume something: your time would have to be worth in excess of $600/hr to justify worrying about 30 secs - or, I could be wrong.

What about the effort of keeping the mounting bases free of corrosion, crud, and being painted over? A lot depends on the plant environment.

You will nearly always get the best possible data taking your data on a solid piece of metal as close to the bearing as possible. Data taken "off axis" will tend to either exaggerate or minimize vibration. I always want to be in line with and as close to the shaft as possible because ultimately "the shaft is the thing"... this is where the energy exits the rotor and enters the housing. The bearing is the point of attack. You want to be as close to that as possible. In my opinion, on the vast majority of machines, your tri-axial mounting point is going to be sub-optimal 80-90% of the time. Any data collection time you save is going to be eaten up back at your desk, scratching your head, muttering to yourself as you try to make sense of the data.

Thanks Guys
I was kind of anticipating this type of response so I am not to surprised by the answers. I agree totally that the time saved would not be worth the effort or loss of good data. But as things change you never know what someone has done to improve and existing technology so that is why I queried about it in the first place.
