The USB6218 and USB4431 are very different as one is a member of the multifunction data acquistion M series family and the other is of the dynamic signal acquisition (DSA) family and cannot be really compared as equal. I always recommend checking the DAQmx C Reference Help( InstrumentsNI DAQText Based Code Support) for the Device Network, share, and ask questions with other members of the NI community.
Also you will require a BNC adapter to connect the strain gauge. The IMI industrial accelerometer cable ( ) is available with BNC termination, which is ideal for the PXIe4464, PXIe4499, NI 9234, and USB4431.
The PCB 052 cable with blunt termination works with the NI 9232 dynamic signal acquisition module. Ask the NI Community. Collaborate with other users in our discussion forums. Search the NI Community for a solution; Request Support from an Engineer. A valid service agreement may be required, and support options vary by country.
The NI USB4431 is a 5channel Ni usb 4431 manually dynamic signal acquisition module for making sound and vibration measurements from integrated electronic piezoelectric (IEPE) and nonIEPE sensors. Four channels on the USB4431 have the signal conditioning for sensors. The fifth channel is an analog output channel.
Furthermore, installing the wrong National Instruments drivers can make these problems even worse. Recommendation: If you are inexperienced with updating National Instruments device drivers manually, we highly recommend downloading the National Instruments NI USB4431 Driver Utility. This tool will download and update the correct National Instruments NI USB4431 driver versions automatically,
