Abstract

SE DA A CONOCER UN HIDROFONO, ESPECIALMENTE PARA SU UTILIZACION EN UN DISPOSITIVO DE SERPENTINA SISMICA MARINA, EN DONDE SE UTILIZA UN SENSOR DE PRESION, SOBRE CUYA SUPERFICIE DE MEMBRANA EXTERIOR SE ENCUENTRAN SUJETOS SENSORES (4,5) PIEZOELECTRICOS. DE ACUERDO CON LA INVENCION EL SENSOR DE PRESION ESTA CONFORMADO A PARTIR DE DOS ZONAS CENTRALES ESENCIALMENTE EN FORMA DE DISCO CON DISCOS (1,2) DE ACERO DIRIGIDOS A UNA DISTANCIA UNO CONTRA OTRO, SIENDO ESTANCOS AL GAS EN LOS BORDES, ESTANDO SOLDADOS ESPECIALMENTE POR MEDIO DE SOLDADURA DE LASER. EL SENSOR DE PRESION ESTA AISLADO ELECTRICAMENTE CONTRA SU AMBIENTE EXTERNO A TRAVES DE UN RECUBRIMIENTO DE RESINA SINTETICA, QUE PUEDE ABARCAR EL SENSOR DE PRESION COMPLETO INCLUYENDO EL AISLAMIENTO DE LAS CONDUCCIONES DE CONEXION. EL HIDROFONO PUEDE FABRICARSE EN DIMENSIONES Y PESO PEQUEÑOS, ES MECANICAMENTE ROBUSTO Y PUEDE SOBRECARGARSE AMPLIAMENTE, ASI COMO SE ENCUENTRA PROTEGIDO CONTRA LA CORROSION Y EL DESGASTE PREMATURO MEDIANTE EL RECUBRIMIENTO DE RESINA SINTETICA.
