I am trying to read data from piezoresistive accelerometer. As you can see on datasheeet, the sensor consist of full bridge strain gauge. For this reason, I tried to read with NI 9237 DSUB strain gage module, but failed. Then I used 9234 accelerometer module using external excitation from power supply. On NI MAX software, I saw some measurement however I was not sure. On block diagram using daq asistant, when I choose the Iex source as external, I got error message. How could I solve this problem? Which module is suitable to acquisite data from this shock piezoresistive accelerometer?
Thank you for help.
I have
NI cDAQ 9188
NI 9234
NI 9237 with DSUB
