I drink the Apple kool aid. No android here. The database would be easily cloud or wifi backed up to a server. I really am curious why this day and age we setup all these measurement definitions for measurements that originate from a handful of time waveform lengths, and stand at the machine to individually acquire a twf for each of them. It seems much more user friendly to record the waveforms and post process. Plus if this is built into the software you could post process into different graphical formats in perpetuity.

Ditto OLi,

I do have experience with a do all computer / vibration analyser / makes toast. At the time Predict DLI, now Azima. WARNING. That was 20 years ago. Turned out a nightmare. When near a certain section of AC drives it would "blue screen of death" each and every time.  Must have been some electrical black magic that electricpete was responsible for. LOL. Who wants to use MS word to write a report in the heat and noise of a paper machine anyway. It took a few weeks to do a survey and then not confidently. We threw it in the bin and got on with CSI.  Job done in a few days. I sincerely hope the CSI influence through KP has improved things. DLI was born with US navy as upstart where no doubt there were no paper machines on aircraft carriers. Hope things have changed for them.  Although 20 years seems a very long time things also move very slowly in large corporations. rgds

Cloud does not exist w/o a network and in a paper machine it is not there that much unless you bring it, also mobile phone based network do have limited access inside paper machines so regardless of OS you do pretty much rely on local storage..... There are systems that have serious postprocessing even Cepstrum.

I'm a daily user of skf last 9'years and have to say whilst it's all I know, there are good and bad points to it. I agree with Big J I like the idea of taking a high res 8-10 sec twf and post processing the living crap out of it in the comfort of my office after.

I see a few machines doing that lately the Betavib
http://betavib.com/

And a company Selling a unit called Vbox3 (can't recall the company name)
http://mtsvibes.com/vbox3 (The owner is ex CSI apparently)




Skf have a system using a Bluetooth sensor last two years and can do routes with a android or iOS tablet but it's still hit and miss, backs up to Aptitude database but limited capability down to resoloution etc.
That said I'm more excited about the new system they have us a promised (database all cloud based) due for release in September.
I've seen an early release of it and it looks promising.

You can run it on a smartphone or tablet, create the route with your phone initially using templates then collect Andy edit the database on the fly or lock it so minions collecting data won't mess anything up if needs be.
Allows vibration readings as well as images from device recording of audio and thermal images from a seek or flir mini smartphone mounted camera to be integrated into the route.

I'm hoping to have a development version in a few weeks. They are using machine learning and analytics for diagnostics and automated reports on the cloud if desired or you can analyse traditionally if you prefer.



Im hoping they manage to deliver something decent, they have been distracted in the past and promised a lot and delivered marginally.

11 out of 10 for honesty. Much appreciated.  Not to say others aren't honest. rgds

I'm going to pipe in here as it looks like there is interest in being able to record a vibration signal to post process at the convenience of your desk. My background in working with offshore rigs was to fly out there to diagnose a turbine problem for instance but while onsite they could not get the event to reoccur, I'd then fly back with "some data" that was essentially normal. Sure enough I'd get a call that the turbine just tripped again and if I could come back out....
I own a service company in the southwest US and a lot of my field work is diagnostics and acceptance testing, I first became interested in the Adash systems solely because of their high resolution and ability to record the "raw" signal for post processing. I liked them for acceptance testing because if I failed a pump and the vendor called asking if took data a certain way that maybe I felt wasn't necessary, then no problem I'd just pull up the recording and post process it however they wanted.
These are true recorders and not just a long waveform, you can record up to four channels and a tach input at 65kHz (25600 LOR) for about 30 hrs or so if you like, then post process in the firmware in the same fashion that you could process live. The firmware does not know the difference it just asks for a signal source and you can choose to be "live" or choose a recording. Since the unit records the digital signal from the DSP board at the same frequency it samples there is no loss of data and no benefit to collect live data over processing a recording. The same firmware that runs in the VA4 units is free to download onto a PC and fully functional, just need a recording to utilize or connect your laptop or tablet to a portable SAB 4404 box to collect live data. I have gotten spoiled (and lazy) and when in the field just record the data and post process later that way i don't have to worry about set up and if during normal analysis i want to go back and get higher resolution, cross channel phase, coast down, etc I can no problem. I even record my bump tests..
The VA3 with the recorder option is under 7k and will record up to three channels at 65kHz for 20 minutes, i have sold them to guys that use on mobile systems or inaccessible systems. Good for slow speed since you can post process with super high resolution. The recorders can also be set to wake up on a trigger such as amplitude or speed change.
