Abstract
Se describe un dispositivo para determinar la distancia (?x) entre cuando menos un alabe (14) y cuando menos la pared (111) que rodea al alabe (14) de una turbomáquina (10), dispositivo que incluye una guía de ondas (40) para conducir ondas electromagnéticas (31, 32) y transmitir las ondas electromagnéticas (31) a través del orificio de la guía de onda adyacente al alabe (14), en dirección hacia el alabe (14), cuando menos un medio (51) conectado a la guía de ondas (40) para transmitir las ondas electromagnéticas (31) en la guía de ondas (40), cuando menos un medio (52) conectado a la guía de ondas (40) para recibir las fracciones reflejadas (32) de las ondas electromagnéticas (31) transmitidas en la guía de ondas (40), y una unidad de evaluación (60) para evaluar la fracción reflejada (32) que va a recibirse de las ondas electromagnéticas (31) transmitidas, la cual incluye medios (61) par comparar las fases de las ondas electromagnéticas (31) que van a transmitirse con las fases de las fracciones reflejadas (32) correspondientes de las ondas electromagnéticas transmitidas (31), en donde por medio de la unidad de evaluación se determina un valor comparativo de fase y de la comparación de los valores de comparación de fase se determina la distancia (?x). La guía de ondas está formada por los menos por dos segmentos de guía de onda (40), los cuales están realizados de diferentes materiales, en los cuales la resistencia a la temperatura y la capacidad de amortiguación para las ondas electromagnéticas, del material aumenta iniciando en el segmento conectado a los medios (51, 52) para transmitir y recibir, en dirección hacia el segmento (42a) que presenta el orificio de la guía de ondas (40).
