<p>The sensor (1) comprises a casing (2) in which is rotatably mounted a rotor (3) which can be coupled for rotation with a rotatable member such as an accelerator pedal (P), and having a pair of transverse arms (15, 16). Each of these arms (15, 16) is connected to a respective arcuately curved core of ferromagnetic material (17, 18) which curves along an arc of a circle co-axial with an axis of (A-A) of the rotor (8). A pair of solenoids (29, 30) is fixed in the casing (2), each solenoid having its longitudinal arcuate axis lying along an arc of a circle co-axial with the axis A-A of the rotor (8), and each associated with a respective core (17, 18) of the rotor (8) in such a way that upon variation in the angular position of the rotor (8) with respect to the casing (2) the angular penetration of the cores (17, 18) into the associated solenoids (29, 30) varies correspondingly, and consequently likewise the inductance of the solenoids (29, 30), likewise varies correspondingly. <IMAGE></p> |
