Abstract

Aparato centrífugo de desgasificación (10) que comprende - un rotor hueco giratorio (20) conectado a una entrada de fluido estacionaria (14) en una parte extrema y a una salida de líquido estacionaria (18) en la parte extrema opuesta, y que presenta un escape de gas (36) para extraer el gas del centro del mismo, - presentando dicho aparato en dicha parte extrema de entrada unos medios (24) para hacer girar dicho fluido y dirigirlo a la pared interior de dicho rotor (20), comprendiendo además el aparato - un sensor giratorio (42) dispuesto para medir el grosor de la capa de un líquido que gira en dicho aparato, y - un árbol (44) que se extiende desde el exterior del rotor (20) al interior de dicha parte de salida, en el que dichos medios (24) para hacer girar dicho fluido comprenden un primer impulsor (26) y en el que dicho aparato comprende además un segundo impulsor (30) en dicha parte extrema de salida, caracterizado por que el sensor (42) está fijado al segundo impulsor (30) o al árbol (44).
