The invention relates to a tachometer (10) for an aircraft wheel (R) mounted on a shaft (E) for rotation about an axis of rotation (X), comprising a stator (20) intended to be fixed to the shaft (E) and a rotor (30) intended to be rotatably connected to the wheel. According to the invention, either the stator or the rotor comprises at least one non-contact sensor (23) having at least two measurement units (28.1, 28.2) adapted to interact with a plurality of targets (37) carried by the other of the stator or the rotor to generate two signals (S1, S2) representative of the wheel speed, the measurement units being angularly offset from each other about an axis (X), in this way, the direction of rotation of the wheel is detected by combining the two signals.
本发明涉及一种用于安装在轴(E)上以围绕旋转轴线(X)旋转的飞行器轮(R)的转速计(10),该转速计包括旨在固定到轴(E)的定子(20)和旨在可旋转地连接至轮的转子(30)。根据本发明,定子或转子中的任一者包括至少一个非接触式传感器(23),其具有至少两个测量单元(28.1,28.2),适于与定子或转子中的另一者承载的多个目标(37)相互作用,以产生表示轮转速的两个信号(S1,S2),测量单元围绕轴线(X)彼此成角度偏移,以便通过组合这两个信号来检测轮的旋转方向。
