Abstract

MONITOR DEL INTERSTICIO DEL ESCUDO DE ALABES DE TURBINA CON AUTO-CALIBRADO. EL SISTEMA PARA MONITOREAR EL INSTESTICIO ENTRE UNA PARTE FIJA DE UNA TURBINA Y SEGMENTOS DE ESCUDO DE ALABES CIRCUNFERENCIALES COMPRENDE UN SENSOR SENSIBLE A LAS CORRIENTES DE FOUCAULT GENERADAS EN CADA UNO DE LOS SEGMENTOS DE ESCUDO PARA PRODUCIR SEÑALES DE ENTRADA REPRESENTATIVAS DEL INTERSTICIO ENTRE CADA SEGMENTO DE ESCUDO Y LA PARTE FIJA DE LA TURBINA. UNOS ELEMENTOS INDICIALES SON TRANSPORTADOS POR EL ESCUDO DE ALABES DE TURBINA PARA CAUSAR QUE EL SENSOR PRODUZCA UNA SEÑAL DE DESPLAZAMIENTO CONOCIDA. UN PROCESADOR RESPONDE A LAS SEÑALES DE ENTRADA Y A LA SEÑAL DE DESPLAZAMIENTO PARA PRODUCIR SEÑALES DE SALIDA INDICATIVAS DEL INTERSTICIO ENTRE CADA UNO DE LOS SEGMENTOS DEL ESCUDO Y LA PARTE FIJA DE LA TURBINA. LAS SEÑALES DE SALIDA TIENEN UNA RELACION PREDETERMINADA CON LA SEÑAL DE DESPLAZAMIENTO CONOCIDA.
