orbit plot using ICP® accelerometer Model: 603C01

[Ibrahem]

Hi All, 

i need to know if i can use the ICP® accelerometer( Model: 603C01) sensor to draw the orbit plot 
the specs of the sensor in the link below

Thx all .

That accelerometer will produce a ± output voltage linear with respect to acceleration in one sensitive axis. I am not sure what you mean by orbit plot, but the output voltage can certainly be plotted as either a positive or negative voltage, corresponding to acceleration in g's.

 Hi Ibrahem,

This article gives more information about Orbit, Timebase, and Shaft Centerline Plots, which is what I believe you are referring to: http://zone.ni.com/reference/en-XX/help/372416A-01/svtconcepts/obt_tbs_shctln/

You'll need X and Y proximity detection in order to use those plots. Hopefully this information, combined with SciManStev's analysis of your sensor provides you an answer to your question. Since that sensor isn't an NI product, I'll have to rely on your analysis of whether your sensor can provide that kind of information. Just from a cursory glance, however, it appears as though your sensor only provides a single vibrational output value, rather than an X-Y position reading.

if you can help me in choosing the best proximity probes to draw the orbit plot i will be grateful
My application is a machine monitoring and i want to draw the plot for a metal rotating shaft

Hi Ibrahem,

We'd be happy to help you select hardware for the monitoring and control of your machines. In order to make an accurate recommendation, we'll need some more information about your specific application. At this site (http://www.ni.com/landing/25/en/), there is a downloadable design guide that will assist you in choosing the proper instruments. Some basic information will be required from you that will help us recommend hardware for your specific application. If you find this information insufficient or this is not the route you would like to take, please let me know.

Thanks.

The best source in my experience for proximty displacement probes is CTC:  https://www.ctconline.com/__proximity_probes_.aspx

These work well with the 9230 modules. 

If you are using accelerometers, you can double integrate these into displacement and then use the integrated signals for your orbit plots. 

Happy to provide more details.
