Abstract

APARATO PARA SIMULAR SEÑALES SENSORIALES DE PASO DE ALABE. UN PROCESADOR PROPORCIONA N SERIES DE VALORES DISCRETOS, ESTANDO PROXIMA CADA SERIE DE VALORES DISCRETOS A UNA SEÑAL SINUSOIDAL Y SIENDO N EL NUMERO DE SENSORES CON LOS QUE UN BVM (MONITOR DE VIBRACION DE ALABE) A SER COMPROBADO SE USA NORMALMENTE. SE DISPONEN N CONVERTIDORES DE DIGITAL EN ANALOGICO, RECIBIENDO CADA UNO DE ELLOS UNA DE LAS SERIES DE VALORES DISCRETOS Y PRODUCIENDO UNA SEÑAL ANALOGICA A PARTIR DE LAS MISMAS. LAS SEÑALES ANALOGICAS TIENEN CRUCES CON EL EJE DE CERO QUE INCORPORAN FORMACION RECONOCIDA SOBRE VIBRACION DE ALABES DE TURBINA. SE DISPONEN N FILTROS, SIENDO RESPONDIENTE CADA FILTRO A UNO DE LOS CONVERTIDORES PARA FILTRAR LAS SEÑALES ANALOGICAS. SE DISPONE CIRCUITERIA PARA PRODUCIR UN IMPULSO DE SALIDA QUE SIMULA UN IMPULSO POR CADA REVOLUCION.
