Abstract

PURPOSE: To improve the reliability of centrifuge operation, by inputting the output of a detector for detecting the rotational speed of a centrifuge rotor into an electronic computer, and conducting required data processing, monitoring operational conditions and error-processing.
CONSTITUTION: The rotational speed of a rotation-detecting disc 6 connected directly to the rotor of a centrifuge is detected by rotation detectors 7, 8. The outputs of the detectors 7, 8 are inputted into the input interface circuit 12 of a microcomputer 11. Required data processing, monitoring operational conditions and/or error-processing are done by an input PIA14 and an output PIA through CUP18, RAM16 and ROM17, and outputted to an output interface circuit 13. The output of the circuit 13 is fed through a driver circuit 19 to a relay 20, so as to properly accelerate, decelerate or stop a motor 3 for driving the rotor of the centrifuge.
