pickup to pc - is the latest trend in vibration analysis and data collection? 1

[edison123]

I recently came across this.

http://www.sequoia.it/en/fast_tracer.htm

They claim

FastTracer can be connected directly to the PC’s USB port and associates a triaxial value in the time and/or frequency domain of the vibrations of the machine being analysed with each measurement point.

Is this true? If anyone has any experience with this type of vibration analysis and data collection, your feedback will be much appreciated. Thanks.

A pdf of their specs is also attached here.

Sounds plausible, there are existing MEMs triaxial accelerometers that have that kind of performance

Thanks IRstuff.

Are they accurate and reliable for measuring large motor/generator vibrations?

Could you please let me know the other OEM's that use this technology?

I'm in the US, so not likely that I would be using Italian sensors, unless I couldn't get any sensors here.

Any country of origin is fine with me. As long as it has been proven to be trustworthy. I am thinking of upgrading from my old swedish hand held model analyzer.

You could roll your own:

this comes with I2L/SPI native interface

Thanks IRstuff.

That stuff still requires an interface between the pickup and the pc?

Sure, unless the PC has built-in I2C or SPI. Note that you'd also need a breakout board for the accel and its required connections.

But, Digikey sells the accel for under a couple of bucks, and you can probably get a USB-based Arduino or similar that supports SPI/I2C.

Thanks IRstuff. I am not competent to build a system. Just an end user here and this new method of pickup to pc seemed novel and simple to me. I am in touch with the OEM but still not convinced about how their sensor, which is 55x30 mm rectangle base, can be fixed on to the curved motor surfaces given the large foot print.
