Hello all,

i am currently using a now antiquated Datapac 1500 for walk around data collection. It is a good instrument, the only downfall is the lack of memory. Soon Rockwell will not be able to support the Datapacs due to lack of repair parts.
I am looking to upgrade to the Enpac 2500, before doing so I would like some opinions on the reliablity of the unit. I have heard some bad things and some good. Please be honest in your opinions. The units are not cheap, dont want to be stuck with an overpriced unit that will not perform to my standards.

Thanks
Jim

Why not look at alternatives to Enpac.

There are several.

Since I work for Datastick Systems I am biased but the handheld analyzer VSA - 1215 does a great job at low cost and is easy to setup and use. www.datastick.com.

Thanks Balancr for the input.

I already have Emonitor software for the Enpac unit. I have been looking at several other vendors, software and hardware cost are the biggest reason I am sticking with the Enpac.

Salam n hello Jimmy,

Why dont you go for a refurbished SKF Microlog CMVA 60? Check out your nearest SKF Agent. A friend of mine purchased it alongwith Prism software at about one fourth of orignial price.

I have experience to use both Microlog CMVA Series and CSI 2130. Both are excellent for routine vibration monitoring. I would like to suggest that you should check CSI 2130 as well. Getting information about its features from nearest available agent won't cost you anything.

We have a Microlog CMVA 60 and CSI 2130 at our plant and we have decided to shift all vibration monitoring to CSI 2130, as we found it pretty smarter than CMVA 60. Its fast n battery life + memory are outstanding. Most probabaly we are going to purchase a second unit of CSI 2130...

Regards,

How well suited is the CSI 2130 for detailed analysis. Can it perform phase, waterfalls, true zoom, bode/nyquist measurements, bump test?

The datapac 1500 is an excellent analysis tool, another reason for keeping the Emonitor software.

Dear Jimmy,

With Advance analysis feature you can have:

1)Bump test on equipment off
2)Bump test on equipment Running
3)Coast down peak hold
4)Coast down peak and phase
5)Rotor bar test motor Current (some additional hardware is required for this feature)
6)Order tracking
7)Synchronous Time Averaging
8)Orbit Plot (you can upload the plots to analysis software as well)
9)Cross Channel Phase
10)In off route mode it has waveform,Spectra,Overall,Third octave,True zoom,Cascade etc.

Moreover i have purchase an additional plug in for "Advance Transient Analysis".

The things i like most about CSI 2130.

1)It is very fast.
2)Almost unlimited memory.Internal memory is 256 MB, while i have an additional 1GB card. But i could never utitlize more than 20% of internal memory during daily measrements(approx 30 m/c's per day).
3)12800 # of lines both in off-route and route mode.
4)End frequency is 4800 KCPM.
5)You can save more than one readings at any point or for whole machine.
6)It can be used as temporay online monitor.(for example, when ever i need, i often record the overall vibration for 5 - 10 minutes and then upload to analysis software. the length of data stored depends on battery life n available memory. If you wish to store data for hours then you can supply it with power to overcome battery problem, n with 5-10 minutes of overall vibration trend it used only 1-3 MB of space approx.)

here is just an overview...
If you wish to have more details, contact me at yaser.ejaz@fatima-group.com. I will send you a comparision chart which i made b/w CSI 2130 & SKF Micrologs.
