Abstract

Sensor angular inductivo, especialmente para un automóvil, con un circuito de oscilador, que genera una señal periódica de tensión alterna y la acopla en una bobina excitadora, con varias bobinas receptoras, cada una de las cuales constituye una estructura de bucle que se repite periódicamente y cuya disposición forma en conjunto dos geometrías de recepción, con un circuito de evaluación para la valoración de las señales inducidas en las bobinas receptoras, y con dos elementos de acoplamiento inductivo desplazables, que influyen sobre la intensidad del acoplamiento inductivo entre la bobina excitadora y las bobinas receptoras, en el que la periodicidad de las estructuras de bucle de las bobinas receptoras en las dos geometrías de recepción es diferente, cada uno de los elementos de acoplamiento presenta una geometría periódica y la periodicidad de los dos elementos de acoplamiento es diferente, la periodicidad de cada una de las estructuras de bucle de una bobina receptora coincide con la periodicidad de la geometría de cada elemento de acoplamiento, y por todo el campo de medición del sensor angular, los números de repeticiones periódicas en las estructuras de bucle de las bobinas receptoras de las dos geometrías de recepción están en una relación mutua no enteramente exacta.
