Wheel mounted electronic tire pressure gauge
First Claim
1. An electronic wheel mounted tire pressure indicating system comprising:
- a wheel unit with a wheel tire;
an electronic strain gauge transducer mounted on a wheel tire valve stem in fluid communication from the interior of said strain gauge transducer to the interior of said wheel tire;
pressure display means mounted on the hub of the wheel mounting said wheel tire;
battery power means mounted with said pressure display means connected through wire means for supplying power to said pressure display means and to said electronic strain gauge transducer; and
manually actuated switch means for supplying power to said electronic strain gauge transducer and said pressure display means only when actuated for checking tire pressure via the tire pressure indicating system.

Abstract
A tire pressure indicating system using valve stem mounted strain gauge transducers circuit connected to a hub mounted display device. A manual switch connects wires of the system for battery power to the strain gauge transducers and for display actuation. Both tires of a dual tire unit are selectively switch actuated for display by a single display unit. The strain gauge transducers used are small and light and the circuit wires that may be quick disconnect connected to the transducer on a wheel tire valve stem and to the hub mounted display device are sufficiently small and light so as to not impose materially adverse unbalance problems on a rotating wheel while the using vehicle is moving down the road.
