Abstract

EL CUERPO BASE (12) Y/O LA MEMBRANA (11) DEL SENSOR DE PRESION (10) CONSTA DE CERAMICA, VIDRIO O UN MATERIAL CRISTALINO. LA MEMBRANA (11) ESTA SOBRE UN LADO QUE SE DIRIGE HACIA EL CUERPO BASE (12) CON UNA CAPA DE PROTECCION (21) QUE CUBRE LA SUPERFICIE LIBRE DE ESTE LADO Y QUE ESTA RECUBIERTO A MODO DE UN ELECTRODO CONDENSADOR (14) POR UNA CAPA DE KARBID DE SILICIO, NIOB O TANTAL. EL CUERPO BASE (12) ESTA SOBRE LA PARTE DIRIGIDA A LA MEMBRANA (11) CON AL MENOS UNA CAPA DE PROTECCION (22) QUE CUBRE LAS SUPERFICIES LIBRES DE LOS LADOS, ETC. EL CUERPO BASE (12) ASI COMO LA MEMBRANA (11) ESTAN UNIDOS ENTRE SI POR MEDIO DE UNA PIEZA DE MOLDEO DE UN LOTE DE SOLDADURA (20) QUE SIRVE PARA MANTENER LA SUJECCION DE LAS DISTANCIAS. ESTE SENSOR DE PRESION SE PUEDE FABRICAR DE UNA SOLA VEZ. LA CARGA DE LA PRESION MAXIMA DE LA MEMBRANA NO SE CORRESPONDE CON LA CONSISTENCIA DE LAS JUNTAS, SINO SIMPLEMENTE CON EL MATERIAL DE LA MEMBRANA. EL SENSOR DE PRESION PUEDE SER UTILIZADA A TEMPERATURAS ALTAS. TAMBIEN SE PUEDE UTILIZAR COMO SENSOR DE PRESION CON ENSAMBLADOS DE FRITA DE VIDRIO.
