すべり検出機構。 In a centrifuge that uses centrifugal force to separate particles with different specific gravity, there is a device that detects whether the rotation speed of the rotating container into which the sample is inserted has exceeded the allowable rotation speed, and a rotation signal from the drive shaft to control the rotation speed. The apparatus is characterized by having a device for detecting a signal from the rotating container and a signal from the drive shaft using a clock reference signal, and detecting any deviation in synchronization between the respective signals. Slip detection mechanism for rotating containers for centrifuges.
