The impression I got from the spec sheet was that the rotation change of voltage was based on the view from behind the body, not from the shaft direction, so below the pot, and if that's the case, then I do want it to increase with counter clockwise rotation when seen from below.
I've just looked at the sheet again , the link was digikey's site, try Here
It looks like I was wrong, the spec sheet needs to be looked at very carefully, their orientation IS based on the shaft rotation direction, so shows clockwise on the diagram in an anticlockwise position from below, if that makes sense.
I've had a rotten cold the last few days, so the brain is full of cotton wool right now, and thinking about anything for more than a few minutes isn't working well.
If the resolution is within 10 degrees, that's way better than anything I can get from the Fine Offset device, and close enough for the sort of reporting I am looking for, and I think that it's a lot tighter than that for this device.
What's making this appealing is that if it's under a good protective shroud so that the bearings are not getting water in to them, the life of this sensor should be very long indeed, and it won't put significant load on the wind vane, which is what's needed in this application.
Thanks all for the feedback, I think it's worth having a go with one of these.
