Abstract

UN SENSOR DE ULTRASONIDO PARA LA DETECCION NO INVASIVA DE BURBUJAS DE AIRE EN LIQUIDOS QUE CIRCULAN POR UNA MANGUERA (80), QUE SE COMPONE ESENCIALMENTE DE DOS MITADES DE CARCASA (10) ACOPLABLES ENTRE SI. PARA EL ACOPLAMIENTO ACUSTICO DE LA MANGUERA (80) CON LOS DOS CONVERTIDORES DE ULTRASONIDO (20) MUTUAMENTE ENFRENTADOS POSEE CADA MITAD DE CARCASA (10) UNA CAMARA (40), QUE ES CERRADA POR UNA MEMBRANA (30) FLEXIBLE Y QUE ESTA LLENA DE UN LIQUIDO (50) BUEN TRANSMISOR DEL SONIDO. EL LIQUIDO (50) DESPLAZADO POR LA MANGUERA (80) COLOCADA ENTRE LAS DOS MITADES DE CARCASA (10) LEVANTA LA MEMBRANA (30) A AMBOS LADOS EN FORMA DE REBORDE (33). CON ELLO SE CREA UN CONTACTO EXCELENTE ENTRE LA CAMARA (40) LLENA DEL LIQUIDO (50) Y LA MANGUERA (80) INDEPENDIENTE DEL DIAMETRO DE ESTA. LA MEMBRANA (30) PUEDE ESTAR CAPSULADA EN LAS PAREDES LATERALES (12, 13) Y ESTAR CURVADA EN FORMA DE MEDIO PUNTO A LO LARGO DE ESTAS.
