Title: Método para la estimación del desalineamiento de placas en reómetros utilizando ultrasonidos
Inventor: ELVIRA SEGURA LUIS
IPC: G01N11/14
Filed: 2013-03-05
Granted: 2015-06-22
Abstract: El objeto de esta invención es una nueva técnica que permite medir el desalineamiento entre placas de un reómetro torsional por medio de ultrasonidos. El desalineamiento entre placas es detectado y cuantificado midiendo las variaciones del tiempo de vuelo de una onda acústica que atraviesa el espacio entre placas viajando por la muestra. La variación del tiempo de vuelo es proporcional a la variación del espesor de la muestra, y por lo tanto, a la variación de la distancia entre placas. La técnica también permite obtener la velocidad de propagación acústica de cualquier muestra, sin más que medir el tiempo de vuelo que invierte la onda ultrasónica en recorrer la distancia establecida entre placas para dos posiciones conocidas.
