Abstract:
A measurement device for measuring the pressure of a wheel (3) of a vehicle, the measurement device comprising a stationary portion (5) and a movable portion (14) for being driven in rotation by the wheel, the stationary portion including a first printed circuit (7) having at least one first track formed thereon defining a first winding, the movable portion including a second printed circuit (16) having at least one second track formed thereon defining a second winding, the second printed circuit being arranged to be connected to a pressure sensor (15), the first winding and the second winding being coupled together to form a wireless communication channel, the measurement device being arranged in such a manner that the pressure sensor is electrically powered by the stationary portion via the wireless communication channel, and in such a manner that uplink data comprising pressure measurement data is transmitted to the stationary portion (5) by the movable portion (14) via the wireless communication channel.
