Abstract
A solids-liquid separating centrifuge with bowl and conveyor members rotated about a common axis at a differential speed has means for sensing torsional vibration of at least one of the members about its axis and providing an output representative of the vibration amplitude, and signal means which provides an indicative signal when the output indicates vibration amplitude above a predetermined level. The indicative signal may operate an alarm, or an automated centrifuge throughput reducing system, or both.
