Abstract
UN METODO PARA COMPENSAR LA DESALINEACION EN UN SISTEMA DE INDICACION DE POSICION DE LAS BARRAS COMPRENDE LAS ETAPAS DE APLICAR UNA CORRIENTE DE EXCITACION AL PRIMARIO DE UN SENSOR PARA INDICAR UNA TENSION GENERICAMENTE LINEAL REPRESENTATIVA DE LA POSICION DE UNA BARRA DE CONTROL SOBRE EL SECUNDARIO DEL SENSOR. LA CORRIENTE DE EXCITACION INCLUYE UNA PRIMERA FRECUENCIA QUE ES SUFICIENTE PARA SUMINISTRAR UNA SALIDA GENERICAMENTE LINEAL PARA EL SENSOR. LA CORRIENTE DE EXCITACION SE MODIFICA POSTERIORMENTE PARA INCLUIR UNA SEGUNDA FRECUENCIA SUFICIENTE PARA SUMINISTRAR LA SALIDA GENERICAMENTE LINEAL CUANDO LA PRIMERA FRECUENCIA ES SUFICIENTE PARA SUMINISTRAR LA SALIDA GENERICAMENTE LINEAL.
