Abstract: A tire pressure monitoring sensor moveable inside a tire includes a housing holding a pressure sensing/transmitting unit, one or more batteries and an antenna for transmitting a signal indicating interior tire pressure. In one embodiment, the components are assembled within the housing such that the center of gravity is along a housing geometric center. During tire rotation, the monitor independently rotates within the tire and is particularly useful for slow-rotating tires, such as those used in gantry systems. Alternatively, the pressure monitoring sensor components are assembled within the housing such that the center of gravity is offset from a housing geometric center. Centripetal force generated during tire rotation causes the monitor to rotate with the tire itself and is useful for faster-rotating tires, such as motor vehicle tires. A tire pressure monitoring system includes the monitor and a receiver positioned outside the tire for receiving the monitoring signals.
