I'm hoping someone has a solution for a problem I need to solve: the issue is to find a means of measuring the pressure in a tire tube (it's equivalent to a 9-inch tire inner tube). It has to be remote, as the tube is in a high speed apparatus, and rapidly speeds up and slows down. The need is to confirm adeq pressure during the slow phase in order to minimize risk of failure during the high speed phase. I cannot use the common tire pressure transmitters that screw on the valve stem (because of balance & side load issues). I've thought of drilling another hole in the wheel for an automotive valve stem transmitter, but would they read pressure in a tube, and besides, how would I go about setting up a receiver? Any clever solutions or adaptations out there that would work for this application?
