Abstract

SE CREAN UNOS DISPOSITIVOS INTENSIFICADORES DE MEDICION (10, 10 ) DE UN MEDIDOR DE CORRIENTE MAGNETO-INDUCTIVO, QUE PERMITEN REALIZAR UN TRATAMIENTO FIABLE DE LAS SEÑALES DE LOS ELECTRODOS DE MEDICION, INCLUSO EN FLUIDOS CARGADOS CON SUSTANCIAS SOLIDAS, SIN AUMENTAR LA CORRIENTE EN LA BOBINA. EL MEDIDOR DE CORRIENTE TIENE EL TUBO DE MEDICION (1) CON AL MENOS DOS ELECTRODOS DE MEDICION (3, 2) Y EL ELECTRODO DE MASA (4) ASI COMO EL DISPOSITIVO DE BOBINA (5) PARA LA CREACION DE UN CAMPO MAGNETICO. UNA PRIMERA VARIANTE DEL DISPOSITIVO INTENSIFICADOR DE MEDICION COMPRENDE, PARA CADA ELECTRODO DE MEDICION, EL PREINTENSIFICADOR (11, 12) UNIDO A EL Y EL CONVERTIDOR ANALOGICO/DIGITAL (13, 14) POSCONECTADO A ESTE. ADEMAS DE ESTO SE HAN PREVISTO EL CADENCIOMETRO (18) QUE ALIMENTA A ESTOS CON UNA SEÑAL DE EXPLORACION, CUYA FRECUENCIA ES SUPERIOR A APROX. 1 KHZ, Y EL SUSTRACTOR (17) POSCONECTADO A ELLOS. UNA SEGUNDA VARIANTE CONTIENE, PARA CADA ELECTRODO DE MEDICION, EL PREINTENSIFICADOR (11 , 12 ) UNIDO A EL Y ABARCA ADEMAS EL CONVERTIDOR ANALOGICO/DIGITAL (13 ) POSCONECTADO DIRECTAMENTE AL PREINTENSIFICADOR (11 ) ASI COMO LA ETAPA DIFERENCIAL (19) POSCONECTADA A LOS PREINTENSIFICADORES Y EL CONVERTIDOR ANALOGICO/DIGITAL (20) POSCONECTADO A ESTA. DESPUES DE ESTOS VIENE EL SUSTRACTOR (17 ).
