Abstract

UN SISTEMA DE TRANSDUCTOR ACUSTICO DE MODO DE VIBRACION EN FLEXION PARA UTILIZARLO CON SISTEMAS DE DISTANCIA DE POR ECO DE IMPULSOS QUE TIENE UNA PLACA DE RADIACION (29 DE LA QUE SE FORMAN UNAS ZONAS ANTINODALES DE ORDEN PAR (A2, A4, A6, A8), CONTANDO DESDE UNA CONEXION DE ACCIONAMIENTO (4) A UN ELEMENTO ACCIONADOR (10) QUE HAY EN EL CENTRO DE LA PLACA, CON UNOS ANILLOS DE APERTURAS (40) PARA REDUCIR LAS AREAS DE RADIACION DE ESAS ZONAS, REDUCIENDO ASI LA CANCELACION EN EL CAMPO LEJANO Y MEJORANDO LA COINCIDENCIA DEL DISPOSITIVO A LA ATMOSFERA EN LA QUE ESTA RADIANDO LA PLACA. LA PLACA ESTA REFORZADA CON UN CAPA INSONORIZANTE (32) COLOCADA EN UN REBORDE (30) DE UNA CARCASA DEL TRANSDUCTOR (22), DE LA QUE SE ENCUENTRA SEPARADA MEDIANTE UNA HOJA METALICA (34) QUE NO SE ADHIERE A LA PLACA Y SE ENCUENTRA PREFERENTEMENTE CUBIERTA POR UN TEJIDO ACUSTICAMENTE TRANSPARENTE QUE TIENE UN TAMAÑO DE POROS LO SUFICIENTEMENTE PEQUEÑO COMO PARA EXCLUIR A LAS PARTICULAS CAPACES DE PROVOCAR DAÑOS.
