Abstract

EN EL SENSOR DE PRESION (11) PROPUESTO, LA PRESION ES TRANSMITIDA A TRAVES DE UN DIAFRAGMA (14) Y UN PERFORADOR (18) A UN ELEMENTO SENSOR PIEZORRESISTIVO (19). EL ELEMENTO SENSOR (19) ESTA IMPRESO SOBRE EL SOPORTE DE UN CIRCUITO HIBRIDO (21). EL CIRCUITO HIBRIDO (21) PUEDE SER COLOCADO DE MODO PARTICULARMENTE SENCILLO SOBRE UN EXTREMO DEL TOPE DEL PERFORADOR (22) O SOBRE UN LADO DEL TOPE (22). EL MONTAJE COMPACTO DEL CIRCUITO HIBRIDO (21) Y DE LOS ELEMENTOS SENSORES PIEZORRESISTIVOS (19) DA COMO RESULTADO UN MODELO RELATIVAMENTE PEQUEÑO Y BARATO. LAS RESISTENCIAS DE PELICULA GRUESA COMPROBADAS Y ENSAYADAS QUE PUEDEN SER APLICADAS FACILMENTE, COMO CERMET O PLASTICO, PUEDEN SER UTILIZADAS COMO ELEMENTOS SENSORES PIEZORRESISTIVOS (19).
