Re: Lego Mindstorms sensors

Yes, the ultrasonic sensor will work with polycarbonate. But I would be concerned about other sources of interference - the high-noise and high-vibration environment, or possibly the pole itself. The ultrasonic sensor has a rather wide beam, so it's possible to see things that aren't straight ahead.

I'm sure you have reasons for considering some kind of proximity device, but I think your best bet would be a touch sensor.
