Hi All
I need to start measuring sound with a ni 9233 board tha we have and use it for accelerometers.
For learning I would start with a cheaper microphone.
Can somebody tell me if this are compatible with ni9233

or

Or please suggest a microphone for about 100$ or less.
Best regards

You would need a preamp with phantom power injection for these mics. If you know how to solder look into the INA217 datasheet and google '5$ mic preamp'
I have a ECM8000 at home and my 5$ preamp (well, 20$ including housing and batteries 😉 5x9V for 45V ) runs nice , however I run it into my soundcard ...
PCB offer IEPE mics IIRR, but not for <100$ 😄

Hi Henrik
Thanks for your help.
In the Behringer site has this
http://www.behringer.com/EN/Products/MIC200.aspx
and this
http://www.behringer.com/assets/PP400_P0492_S_EN.pdf
Wich this I must use?
This pre-amp is better thant the Phantom PH-1 ?
This is ok for pre-amp the Behringer microphone? But the out put of the first has 3 pins and Ni9233 has a BNC input.
Can you help me how to connect it?
Sorry for I suppose basic questions, but as you know I am a noise begginer.
My experience (there is a very expensive equipement B&K in market) is to apply the microphone near the car wheel and mesure the noise tire/road.
I would learn with cheaper equipement, understand the outputs and after that maybe we can buy a better equipement.
Best regards
