Hi. I'm new to labview and data acquisition so please excuse the newbie question:
What is the best way to read a 0-30mv output from a load cell or strain gauge? Does NI make DAQs for this voltage range? Can the same DAQ be used as would be for reading a 0-5V signal (is the accruacy of the DAQs enough to get good readings from a 0-30mV device).
Without getting too deep into the electronics, basically, you need a load cell amplifier, or strain gauge amplifer. Google it. With an amplpifer, you can "convert" the 0..30mV to 0..5V or similar.
I agree with Arrow on the 9237 module for bridge measurements. If you have any further questions on the device please feel free to post them here and I'd be happy to help.
