Abstract

Système de commande (50) pour instrument centrifugeur (10). Il échantillonne la vitesse de l'axe (34) à un premier et à un second instants de mesure afin de générer un signal indiquant l'accélération effective de l'axe. Le signal d'accélération effective est comparé à une accélération de référence de manière à déterminer si un rotor (18) est présent sur l'axe.
