How to measure a charge accelerometer with a NI 9234 device?

[Clecio]

Dear, I have a NI 9234 and would like to measure a charge accelerometer, Bruel&Kjaer, type 4384 (see attachment). Is it possible? What I need to do?

I tried to measure directly but I didn't see any signal.

Thanks.

Hi Clecio,

This is a charge accelerometer. It is different from the IEPE accelerometers that outputs a voltage signal.

You need a charge amplifier. Then according to the charge amplifier output we can select an appropriate module to measure the signal.

It is not possible to measure charge accelerometers with NI 9234 directly.

Best Regards,
