Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE DETECCION DE CUERPOS EXTRAÑOS PRESENTES EN LA SUPERFICIE DE UN CRISTAL QUE SE CARACTERIZA POR COMPRENDER UNA PRIMERA PLACA QUE TIENE UN PRIMER ESPESOR Y QUE COMPRENDE UN TRANSDUCTOR QUE COOPERA CON UNA PRIMERA CARA DE DICHA PRIMERA PLACA, PUDIENDO DICHO TRANSDUCTOR EMITIR UNA SEÑAL ULTRASONORA DE FRECUENCIA F{SUB,T} Y PUDIENDO RECIBIR UNA SEÑAL ULTRASONORA REFLEJADA SOBRE UNA SEGUNDA CARA DE LA PRIMERA PLACA, SIENDO LA VARIACION DE LA SEÑAL REFLEJADA REPRESENTATIVA DE LA PRESENCIA O DE LA AUSENCIA DE CUERPOS EXTRAÑOS SOBRE DICHA SEGUNDA CARA ENFRENTE DE DICHO TRANSDUCTOR. ESTE DISPOSITIVO SE CARACTERIZA ASIMISMO PORQUE LA FRECUENCIA FT SE ELIGE PARA SATISFACER LA SIGUIENTE RELACION: DONDE F{SUB,K} = K.V/2E ES LA FRECUENCIA DEL KESIMO MODO PROPIO DE LA CAVIDAD RESONANTE QUE CONSTITUYE LA PRIMERA PLACA DE VIDRIO, SIENDO K UN NUMERO ENTERO NO NULO, V LA VELOCIDAD DE PROPAGACION DE LA ONDA ULTRASONORA EN EL MATERIAL CONSTITUTIVO DE LA PRIMERA PLACA, YE EL ESPESOR DE LA PRIMERA PLACA.
