Abstract

SENSOR DE PRESION, QUE COMPRENDE UN SOPORTE RIGIDO (10) Y UN DIAFRAGMA (20) QUE TIENE UNA PORCION PERIFERICA FIJADA POR UNA CAPA DE COLA (30) AL SOPORTE (10) Y UNA PORCION CENTRAL ESPACIADA DEL SOPORTE (10) Y QUE COMPORTA, SOBRE SU SUPERFICIE ENFRENTADA AL SOPORTE (10), POR LO MENOS UN RESISTOR DE PELICULA GRUESA (R) QUE ACTUA COMO UN TRANSDUCTOR PIEZO-RESISTIVO, SIENDO EL DIAFRAGMA (20) APTO PARA DEFORMARSE ELASTICAMENTE HACIA EL SOPORTE (10) CUANDO SE EJERCE UNA PRESION SOBRE SU OTRA SUPERFICIE, CARACTERIZADO PORQUE LA SUPERFICIE (10A) DEL SOPORTE (10) QUE SE CONECTA AL DIAFRAGMA (20) ES PLANA, Y PORQUE LA CAPA DE COLA (30) TIENE UN ESPESOR CALIBRADO DE MODO QUE LA DISTANCIA (D) ENTRE EL DIAFRAGMA (20) Y LA SUPERFICIE (10A) DEL SOPORTE (10) EN REPOSO SEA SUSTANCIALMENTE IGUAL A LA DEFLEXION DEL DIAFRAGMA (20) CORRESPONDIENTE A LA PRESION MAXIMA PREDETERMINADA MEDIDA.
