Abstract

EN EL SENSOR DE PRESION PRESENTADO, LA PRESION ES TRANSMITIDA A TRAVES DE UN DIAFRAGMA (14) Y DE UN PERFORADOR (18) A UN ELEMENTO SENSOR PIEZORRESISTIVO (19). EL ELEMENTO SENSOR (19) ESTA IMPRESO EN EL SUSTRATO DE UN CIRCUITO HIBRIDO (22) Y CONSTA DE VARIAS PISTAS DE RESISTENCIA (38, 39) COLOCADAS UNA ENCIMA DE LA OTRA EN CAPAS, EN PARTICULAR CON FORMA DE PIRAMIDE. ESTO HACE QUE SEA PARTICULARMENTE SENCILLO TRANSMITIR LA PRESION EN EL SENSOR DE MANERA CONTROLADA. ADEMAS, EL CIRCUITO HIBRIDO SE ENCUENTRA EN UN EXTREMO DEL TOPE DEL PERFORADOR (23). EL MONTAJE COMPACTO DEL CIRCUITO HIBRIDO (22) Y DEL ELEMENTO SENSOR PIEZORRESISTIVO (19) PROPORCIONA UN MODELO RELATIVAMENTE PEQUEÑO, BARATO, PERO UNA GRAN SEÑAL DEL SENSOR Y RELATIVAMENTE SIN ERRORES.
