Abstract
MONITOR DE LA TEMPERATURA DEL ESCUDO DE ALABES DE TURBINA. EL SISTEMA PARA MONITOREAR LA TEMPERATURA DE UNA PLURALIDAD DE SEGMENTOS DE ESCUDO DE ALABES DE TURBINA INCLUYE UN ELEMENTO INDICIAL TRANSPORTADO POR CADA SEGMENTO DE ESCUDO. UN SENSOR PRODUCE SEÑALES DE ENTRADA EN RESPUESTA A ESTE ELEMENTO INDICIAL. UN SENSOR DE TEMPERATURA MIDE LA TEMPERATURA DEL SENSOR QUE PRODUCE LAS SEÑALES DE ENTRADA. UN PRIMER CIRCUITO, SENSIBLE AL SENSOR DE TEMPERATURA, CORRIGE LAS SEÑALES DE ENTRADA PARA COMPENSAR LOS EFECTOS DE LA TEMPERATURA SOBRE EL SENSOR. UN SEGUNDO CIRCUITO DETERMINA LA TEMPERATURA DE CADA SEGMENTO DE ESCUDO EN BASE A LAS SEÑALES DE ENTRADA CORREGIDAS.
