ABSTRACT:
A centrifugal separator apparatus for separating a composition to a substantially solid portion and a substantially liquid portion. A dual mode vibration sensor is located radially outward from a shaft utilized for rotating a bowl. The vibration sensor for sensing the radial vibration of the bowl during rotation. Upon the vibration sensor sensing radial vibration above a first predetermined threshold or a second predetermined threshold, a signal is sent to a controller that activates a D.C. brake or frequency inverter to stop the rotation of the bowl. Further, in another embodiment, the centrifugal separator includes a directing member within the bowl for directing the composition outwardly toward the wall of the bowl during rotation to increase the separation of the liquid and the solids.
