Abstract

UN SISTEMA SENSOR PASIVO (14) QUE UTILIZA ENERGIA ULTRASONICA. EL SISTEMA INCLUYE AL MENOS UN SENSOR DE VIBRACION ULTRASONICA (10) Y UN SISTEMA DE ACTIVACION Y DETECCION ULTRASONICA (20,22,24,25). EL SENSOR (10) TIENE LA MENOS UNA FRECUENCIA DE VIBRACION QUE ES UNA FUNCION DE UNA VARIABLE FISICA A DETECTAR. EL SISTEMA DE ACTIVACION Y DETECCION ULTRASONICO EXCITA EL SENSOR Y DETECTA LA FRECUENCIA DE VIBRACION MEDIANTE LA CUAL DETERMINA UN VALOR DE LA VARIABLE FISICA. EL SENSOR INCLUYE (VER FIG.2-4) UNA CARCASA, UNA MEMBRANA ADOSADA A LA ANTERIOR Y QUE RESPONDE A LA VARIABLE FISICA, UNA VIGUETA DE VIBRACION ADOSADA A LA CARCASA EN UN EXTREMO Y UN CONECTOR, ADOSADO A LA MEMBRANA A UNA PEQUEÑA PARTE DE LA VIGUETA DE VIBRACION, QUE LA DOBLA EN RESPUESTA A UN MOVIMIENTO DE LA MEMBRANA.
