Abstract

SISTEMA Y METODO PARA VIGILAR LA VIBRACION DE UNA PLURALIDAD DE ALABES DE TURBINA CONFIGURADOS EN UNA FILA, INCLUYENDO EL SISTEMA UN PRIMER Y UN SEGUNDO PERCEPTORES PARA GENERAR UNA PRIMERA Y UNA SEGUNDA SEÑALES DE ENTRADA, RESPECTIVAMENTE, CUANDO ES DETECTADO UN ALABE DE TURBINA. EL PRIMERO Y EL SEGUNDO PERCEPTORES ESTAN MONTADOS PARA DETECTAR, EN ESENCIA SIMULTANEAMENTE, EL MISMO ALABE DE TURBINA. CIERTA CIRCUITERIA COMPARA LA PRIMERA Y LA SEGUNDA SEÑALES DE ENTRADA CON OBJETO DE DETECTAR UN DESPLAZAMIENTO AXIAL. UN DISPOSITIVO DE SALIDA RESPONDE AL DESPLAZAMIENTO DETECTADO.
