Yes, I just got a tube of silicone I had laying around the house and
encased the whole thing in it. If I remember the tech sheet correctly,
the newer DS18b20's are entirely waterproof (old ones had issues) so
you really only need to encase the leads. I did the whole thing as the
sensor is pulling the temp read off of the ground wire anyways so
might as well be safe.

I've seen it done for potting electronics on ROV's. In that case they
had the electronics in a small plastic enclosure and just filled the
enclosure with wax when done.

I think thats what Hobby-Boards uses, might be worth sending them an email.
