Abstract

Dispositivo de diagnosis para el reconocimiento de conexiones falsas o interrupciones de la línea de un sensor inductivo (1) que consta de una bobina arrollada alrededor de un núcleo magnético, cuya señal de salida es convertida en una señal digital de sensor (Vsalida) para el procesamiento posterior en un dispositivo de control o de regulación (4) en una electrónica de evaluación (3), con un divisor de la tensión (7) conectado entre las conexiones (5, 6) del sensor inductivo (1), al que se alimenta una tensión de referencia (Vref ) en su toma (8), a través de una resistencia (R), con un dispositivo de evaluación (14, 15), en el que se acondiciona la señal de diagnosis (Vdiag) que se puede tomar en la toma (8)y se compara la señal acondicionada con valores umbrales (S1, S2, S3, S3''), siendo reconocida una conexión errónea o una interrupción de la línea cuando se exceden o no se alcanzan dichos valores umbrales.
