Vibration Measurument (NI 9234)

[sefa54]

Hi

I try to make vibration measurument using CompactRIO 9025 and NI 9234.

I use scan engine and NI Sound and Vibration toolkit.

Even thought I specify all required informations, I can not see output what I should see.

My sensor sensivity: 9.95 mV/g

My measurument is just X-axis (The sensor is connected to the AI1 pin of NI 9234)

AI1 of NI 9234 is adjusted to "IEPE AC Coupled".

My shaker applies "1-g" vibration to the sensor, but I read irrelevant value from LabVIEW.

I am sharing required photos..

Any help ??

Hi sefa54,

Could you provide information about your sensor? Is it an IEPE device?

Further, if you could upload your code to view that would better enable the community to help.

When you say values are irrelevant, what are you expecting? What do you anticipate the RMS value of this signal to be?

The problem was because of the sound and vibration tool. I removed all of them and used RMS Value point by point function. So for now, the program runs as I wanted.

Thanks for your care..
