Centrifuge with rotor having identification elements arranged along the circumference of a circle whose center coincides with the rotor's axis of rotation

摘要

A centrifuge includes a rotor, and a motor for rotating the rotor. At least three identification elements provided on the rotor are arranged along a circumference of a circle whose center coincides with an axis of rotation of the rotor. An angular interval between prescribed two of the at least three identification elements indicates a maximum allowable rotational speed of the rotor. One or more of the at least three identification elements indicates a type of the rotor. A sensor operates for detecting the at least three identification elements during rotation of the rotor. The angular interval between the prescribed two of the at least three identification elements is measured in response to an output signal from the sensor to detect the maximum allowable rotational speed of the rotor. The type of the rotor is detected in response to the output signal from the sensor.
