Abstract
Procedimiento de medición de frecuencias de vibración de porciones (2) de un cuerpo (3) giratorio utilizando detectores (C1 a C8) dispuestos alrededor del cuerpo giratorio y delante de los cuales pasan las porciones, convirtiendo mediciones de los detectores en espectros frecuenciales, caracterizado porque los detectores están repartidos regularmente, en sentido angular en cada red, en varias redes (A, B, C) con números diferentes, en especial números primos entre sí, de detectores, no perteneciendo todos los detectores de una red a otra red que tenga un número superior de detectores, se obtiene un espectro para cada una de las redes, y porque se llevan a cabo comparaciones de los espectros de las redes para seleccionar líneas de los espectros y considerar como frecuencias de vibración las frecuencias de las líneas seleccionadas.
