Abstract
Devices for transmitting signals from a rotatable tire to a stationary receiver which correspond to the internal pressure of the tire. In one embodiment, a Bourdon tube communicates with internal tire pressure to regulate the magnetic gap of an electromagnetic induction configuration. Changes in the magnetic gap result in corresponding changes in an output signal strength. In another embodiment of the invention, a bellows is provided in communication with tire pressure for regulating the position of the core of an LVDT. The core position and, accordingly, the output of the LVDT corresponds to tire pressure. In yet another embodiment, strain gauges or other appropriate electrical signal generators are connected to the tire and interconnected with a rotating race. A plurality of ball bearings are maintained in a preloaded condition between the rotating race and a stationary race, the latter race communicating signals to a tire pressure meter or the like.
