Abstract
EN ESTE SENSOR DE PASO MASICO DE EFECTO CORIOLIS (40, 50, 60, 70), QUE SE DEBE MONTAR EN UNA TUBERIA MEDIANTE UN ELEMENTO DE CONEXION (402, 403; 502, 503; 602, 603; 702, 703) DEL LADO DE LA ENTRADA Y OTRO DEL LADO DE LA SALIDA, EL SISTEMA OSCILANTE PUEDE SER EXCITADO POR VIBRACIONES PARASITAS QUE CONTENGAN UNA FRECUENCIA IGUAL A LA DE RESONANCIA DEL SISTEMA OSCILANTE DE MANERA QUE EL RESULTADO DE LA MEDIDA QUEDE FALSEADO. EL SISTEMA OSCILANTE COMPRENDE COMO MINIMO UN TUBO DE MEDIDA (401; 501; 601; 701, 701'') ATRAVESADO EN SERVICIO POR UN FLUIDO A MEDIR. MEDIANTE UN MONTAJE ELECTROMAGNETICO DE EXCITACION (1, 2, 3, 4, 10), SE EXCITAN LAS OSCILACIONES DEL SISTEMA, QUE CONSTA AL MENOS DE UNA BOBINA DE EXCITACION (15; 251, 252; 35) DE BAJA RESISTENCIA OHMICA Y ALIMENTADA POR UNA FUENTE DE CORRIENTE DE EXCITACION (6, 7), DE UN NUCLEO (13, 23, 33, 43, 53) QUE CONTIENE UN IMAN PERMANENTE (12; 221, 222; 32; 42; 512, 522) Y DE UN INDUCIDO (14, 24, 34, 44, 54, 104). EN PARALELO CON LA BOBINA DE EXCITACION SE ACOPLA UN CONDENSADOR, CUYA CAPACIDAD (C) SE ELIGE EN FUNCION DE LA INDUCTANCIA (L) DE LA BOBINA DE MANERA QUE LA FRECUENCIA DE RESONANCIA DEL CIRCUITO ELECTRICO EN PARALELO FORMADO POR EL CONDENSADOR Y LA BOBINA DE EXCITACION SEA APROXIMADAMENTE IGUAL A LA FRECUENCIA DE RESONANCIA MECANICA DEL SISTEMA OSCILANTE. SE MONTA UN SENSOR (406, 407; 506, 507; 606, 607; 706, 707) PARA LAS OSCILACIONES DEL LADO DE LA ENTRADA O DEL LADO DE LA SALIDA, SIEMPRE A LA MISMA DISTANCIA ENTRE EL CENTRO DEL TUBO DE MEDIDA Y EL ELEMENTO DE CONEXION DEL LADO DE LA ENTRADA O DE LA SALIDA.
