Re: Potentiometers to the cRIO, what resistance?

Sensitivity is not really an issue for a potentiometer. The way it's connected, you're just producing a voltage output. The voltage depends on the ratio of resistances, and the absolute resistance values are not important.

A lower resistance is theoretically going to be less noisy, as any stray noise source will have an easier path to ground and thus put less voltage on the signal.

Read the thread Eric linked to for more specific advice.
