The magic words are "non condensing". When I look into my loop after a dive I see condensation.

I was thinking that its only necessary to have dry gas around the sensor area, no need to do the whole loop, so would it not be possible to put hydroscopic membranes at front and back of the sensor chamber ?
Must admit I don't know a great deal about air flow through these but o2 sensors dont seem to have a problem or is that just down to the size of the o2 molecules ???
Just a thought.
