Method for measuring pressure in an aircraft tire

Abstract

Method for measuring pressure in an aircraft tire. Method (200) for measuring pressure in a tire by two surface wave temperature and pressure measuring cells (261, 262), comprising: generation (201) of a first and a second plurality of excitation signals (Ex1, Ex2) in a first frequency band (Bf1) and in a second frequency band (Bf2) disjoint from the first band, and transmission (202) of the excitation signals to the cells; generation (203) by the cells of a first and a second plurality of response signals (Rep1, Rep2) in the first and second frequency bands; determination (205) of reference response signals (Rep1Ref, Rep2Ref) and their corresponding frequencies (f1, f2) among the first and second plurality of response signals (Rep1, Rep2);Determination (206, 207) of temperature (Tmes) and pressure (Pmes) in the tire from cell conversion laws, and determined frequencies.
