Abstract:
A centrifuge comprising:a rotor; a motor for rotating the rotor; at least three identification elements provided on the rotor and arranged along a circumference of a circle whose center coincides with an axis of rotation of the rotor, wherein an angular interval between prescribed two of the at least three identification elements indicates a maximum allowable rotational speed of the rotor, and one or more of the at least three identification elements indicates a type of the rotor; a sensor for detecting the at least three identification elements during rotation of the rotor, and outputting a signal representing results of said detecting; means for measuring the angular interval between the prescribed two of the at least three identification elements in response to the signal outputted from the sensor to detect the maximum allowable rotational speed of the rotor; and means for detecting the type of the rotor in response to the signal outputted from the sensor.
