CENTRIFUGAL MACHINE AND METHOD FOR DISCRIMINATING STATE OF DISCRIMINATOR DETECTING SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a centrifugal machine which is excellent in stability and does not rotate a rotor at a speed above the allowable rotational speed of the rotor since it can handle all the rotors irrespective of the presence/absence of a magnet of a discriminator and can confirm the normal or abnormal state of a Hall element and to provide a diagnostic circuit which can easily confirm the short circuit or disconnection of a detection mechanism part including the Hall element. SOLUTION: A confirmation means 7 for recognizing the actuation state of the Hall element 6 which is a discriminator detecting sensor for reading the magnet 5 of the discriminator fitted to the rotor 1 is installed.
