Abstract

SE DESCRIBE UNA CONFIGURACION DE CIRCUITOS (30) PARA UN SENSOR DE POSICION INDUCTIVO, CUYA DISPOSICION DE BOBINA DE MEDICION PRESENTA VARIAS BOBINAS DE MEDICION, QUE POR LO MENOS FORMAN DOS GRUPOS, DE LAS CUALES CADA UNA SUMINISTRA UNA SEÑAL DE BOBINA DE MEDICION, QUE SE MODIFICA CON LA POSICION A COMPROBAR. LA CONFIGURACION DE CIRCUITOS ABARCA UN CIRCUITO DE CALCULO, EL CUAL PARA LA GENERACION DE UNA SEÑAL DE MEDIDA, POR LO MENOS ENLAZA ENTRE SI DOS SEÑALES DERIVADAS DE LAS SEÑALES DE LAS BOBINAS DE MEDICION DE ACUERDO CON UN ALGORITMO PREFIJADO. PARA ALCANZAR UNA ELEVADA RESOLUCION Y UNA GRAN PRECISION DE MEDICION CON UN GASTO EN CIRCUITOS LO MAS BAJO POSIBLE, ABARCA LA CONFIGURACION DE CIRCUITOS (30) UN MULTIPLEXOR (33), CON CUYA AYUDA SE PUEDE ALIMENTAR UNA SELECCION VARIABLE DE SEÑALES DE BOBINAS DE MEDICION AL PROCESADO POSTERIOR.
