Abstract
A plurality of pressure sensors are provided in a tire of an aircraft landing gear, such sensors being carried by the same stem assembly that has the inflation-deflation valve for the tire. A communication microcircuit is provided in the stem. The communication microcircuit is connected to one coil of a stem transformer, with the other coil of the stem transformer being electrically connected to one coil of an axle transformer. The other coil of the axle transformer is coupled to an axle communication circuit which powers the axle and stem circuits and polls the sensors to determine tire pressure.
