You can always glue a magnet to the main shaft and some kind of reed switch close enough to get pulses. You can use bicycle speed sensor even. It's hermetic, reliable and cheap

You can always use a simple diode and capacitor to filter signal. Low power diode anode to VSS sensor and 4.7uF 30V paralel to MPGuino. That should filter all the noise.
