Patent ID: 6856245

Claim:
A sensor device mountable on a valve stem of an inflatable tire of a vehicle, having an actuating pin adapted to be depressed by a component of a gauge or connecting fixture of a compressed air line coupled to said valve stem, comprising: a housing defining a closed chamber, having a first threaded opening permitting said housing to be threaded onto said valve stem, and a second opening; means supported on said housing engageable with said actuating pin of said valve stem for depressing said actuating and thereby opening said valve stem when said housing is threaded onto said valve stem, intercommunicating the interiors of said tire and said housing; a valve disposed in said second opening having an actuating pin adapted to be depressed by said component of said air gauge or line connecting fixture to provide a passageway through said housing when one said housing is mounted on said valve stem; means disposed on said housing for sensing the pressure within said chamber; means connected to said sensing means for receiving and processing signals therefrom corresponding to sensed pressure; and means coupled with said receiving and processing means for transmitting processed signals corresponding to said sensed pressures.
