Abstract

EN MUCHAS INSTALACIONES DE CARACTER INDUSTRIAL, EXISTEN DISTINTOS TIPOS DE ALIMENTACIONES ELECTRICAS TANTO EN CORRIENTE CONTINUA COMO ALTERNA, ASI COMO SISTEMAS GENERADORES DE INTERFERENCIAS ELECTROMAGNETICAS COMO PUEDEN SER MOTORES, BOBINAS, FUENTES CONMUTADAS, CAMPOS MAGNETICOS, ETC. CONSECUENTEMENTE LA TRANSMISION DE SEÑALES HACIA LOS SISTEMAS DE MONITORIZACION O ADQUISICION DE DATOS, PUEDE VERSE AFECTADA POR LA INDUCCION DE RUIDOS, PRESENCIA DE BUCLES DE MASA Y OTROS EFECTOS NO DESEABLES. LA PRESENTE INVENCION RECOGE UN METODO PARA SOLUCIONAR DICHO PROBLEMA, DESACOPLANDO GALVANICAMENTE LA FUENTE DE SEÑAL Y EL CIRCUITO DE MEDIDA MEDIANTE LA TRANSFORMACION DE LA MAGNITUD DE ENTRADA A VARIACION DE FRECUENCIA, SIENDO TRANSMITIDA DICHA VARIACION POR LA FIBRA OPTICA, PERMITIENDO TRANSMITIR SEÑALES DESDE CONTINUA HASTA 100 KHZ COMO PUEDE APRECIARSE EN LA FIGURA QUE PRESENTA LA CURVA DE RESPUESTA PARA DISTINTAS FRECUENCIAS (FIG. 1).
