DAQ board usually convert voltages, so the first thing you need is a simple hardware solution to convert resistance in voltage. A 1/2 of full bridge setup is fine for this. You can solder it yourself or use one of the signal-conditioning modules NI sales.
If your board has converted the voltages, you can take advantage of the extensive calculation options available in LabVIEW. The documentation of the senders will give you a hint on the lineairisation calculations you need to perform.
