In a method for controlling a centrifuge (100) comprising a rotor (106) and a drive component (104) for the rotor (106), an acoustic signal (AS) is received, at a computing device (102), via a sound transducer (108) located proximate to the rotor (106) of the centrifuge (100). The acoustic signal (AS) is pre-processed, by the computing device (102), by emphasizing at least one predetermined signal feature of the acoustic signal (AS), the signal feature indicating an abnormal operation of the centrifuge (100). An abnormal operation of the centrifuge (100) is detected, by the computing device (102), by processing the emphasized signal feature. An alarm signal and/or a termination signal (212) is generated, by the computing device (102), if an abnormal operation of the centrifuge (100) is detected.
A method for controlling a centrifuge (100) comprising a rotor (106) and a drive component (104) for the rotor (106), the method comprising:
The method of any of the preceding claims, wherein the computing device (102):
The method of any of the preceding claims, wherein the computing device (102) calculates an acoustic signal magnitude (ASM) from the acoustic signal (AS).
A centrifuge (100) comprising:
