Abstract
EN UN SENSOR (12) PARA DETERMINACION DE LA PRESION O DE LA FUERZA SE PRESIONA EN UN SOPORTE (10) UNA RESISTENCIA DE CAPA GRUESA (11). EN EL ESTADO AUN BLANDO DE LA RESISTENCIA DE CAPA GRUESA (11) SE ESTABLECE UNA PIEZA DE CONDUCCION DE FUERZA (13) EN LA RESISTENCIA DE CAPA GRUESA Y SE ENDURECE LA PIEZA DE MONTAJE ASI ENGENDRADA. ASI SE PRODUCE UN SENSOR (12) CON UNA DISTRIBUCION REGULAR DE CARGA SOBRE LA TOTAL RESISTENCIA DE CAPA GRUESA DE MODO QUE SUS CURVAS DE TOMA TRANSCURREN LINEALMENTE SIN TENSION PREVIA EN LA ZONA DE COMIENZO.
