The system for automatically balancing a centrifuge in operation comprises a system for selectively displacing a mass of fluid inside at least one hollow horizontal tube (25) incorporated in the rotary arm (20), together with an unbalance measuring circuit (7 to 14) for the rotary arm (20) which may be out of balance. The unbalance measuring circuit (7 to 14) includes sensors (7) preferably disposed on the stand (23) of the centrifuge, circuits (8 to 14) for processing the signals delivered by the sensors in order to deliver alarm signals or signals for controlling rebalancing in the event that an unbalance is detected, and control means (4) for controlling said system for selectively displacing a mass of fluid, said control means responding to the rebalancing control signals delivered by the unbalance measuring circuit (8 to 14) in order to give rise to selective displacement in real time of a mass of liquid fluid inside said hollow horizontal tube (25), preferably in conjunction with the displacement of a free piston (6), thereby dynamically balancing the rotating arm (20) of the centrifuge.

A system for automatically balancing a centrifuge in operation, the centrifuge including a rotary arm including at least one horizontal tube mounted on a turret for rotation about a vertical axis relative to a stand, the balancing system comprising a system for selectively displacing a mass of fluid inside said hollow horizontal tube, and a circuit for measuring any unbalance of the rotary arm which may be out-of-balance, and the circuit for measuring the unbalance comprising sensors disposed on the centrifuge, circuits for processing the signals delivered by the sensors in order to deliver alarm signals or rebalancing control signals in the event of unbalance being detected, and control means for controlling said system for selectively displacing a mass of fluid, said control means responding to rebalancing control signals delivered by the unbalance measuring circuit in order to give rise to selective real time displacement inside said hollow horizontal tube of a mass of fluid for dynamically rebalancing the rotating arm of the centrifuge.
