摘要
A device and electric circuit mounted on a wheel of a vehicle and to transmit via bearings an electrical signal for measurement of parameters such as the pressure and temperature of the tire. The measurement is made based on the conduction state of a semiconductor element coupled to a sensor sensing the tire pressure and/or temperature. Specifically observed are three resistances of sufficient different values: the resistance of a semiconductor element in the on-state, a resistance Ro two orders of magnitude greater than the preceding one and the internal resistance of at least one semiconductor element in the off-state. The sensor and circuit ar integrated in a standard valve. In one embodiment, it is possible to operate an electric element mounted on the wheel.
