Abstract

UN TRANSMISOR BIFILAR ANALOGICO EXISTENTE TIENE UN MODULO DETECTOR, UN CIRCUITO DE EXCITACION ANALOGICO, Y UN CIRCUITO DETECTOR ANALOGICO QUE PROPORCIONA UNA SALIDA REPRESENTATIVA DE UNA VARIABLE DE TRATAMIENTO DETECTADA, TAL COMO UNA PRESION, A UN CIRCUITO CERRADO BIFILAR DE CORRIENTE. EL CIRCUITO DE DETECCION ANALOGICO ES RETIRADO Y SUSTITUIDO POR UN APARATO QUE INCLUYE UN CONVERTIDOR DIGITAL QUE CALCULA DIGITALMENTE LA SALIDA DEL TRANSMISOR. LA SALIDA SE MEJORA CALCULANDO LA CORRECCION DE LINEALIDAD. EL CIRCUITO DE EXCITACION ANALOGICO PUEDE SER TAMBIEN REEMPLAZADO POR UN CIRCUITO DE EXCITACION SUSTITUTIVO. EL CIRCUITO DE EXCITACION SUSTITUTIVO Y EL CONVERTIDOR DIGITAL PUEDEN ESTAR ACTIVADOS EN SERIE PARA CONTROLAR LA CORRIENTE DE ACTIVACION. UNA BOMBA DE CARGA PUEDE SER ACOPLADA AL CIRCUITO CERRADO PARA EQUILIBRAR LA INTENSIDAD EN EL CIRCUITO EN SERIE. EL CONVERTIDOR DIGITAL PUEDE PROPORCIONAR TAMBIEN AJUSTES ELECTRICOS DEL INTERVALO Y DEL CERO.
