And I don't see how there could be any significant difference between unscrewing a valve cap and unscrewing a small sensor as the effort involved is virtually identical. Unless I am missing something a flow-through sensor (if installed at the end of the valve stem) adds nothing but greater weight/complexity.
other than it would create undo wear on the rubber o ring used to seal it, cause the alarm to go off, and the sensors are installed tighter than a cap and could conceivably cause undo stress on the stem, there is no difference
, as far as the greater weight and complexity, weight difference is likely immeasurable, and complexity? of what?
if you have had the non flow through sensors and removed then to ad air, you would find that the rubber o rings stick to the valve stem and are nearly impossible to re insert rendering the non flow through sensor useless until replacement o rings are installed or found and installed.
If you are going to have sensors and you are going to at some time add air, flow though are the way to go imho.
