Abstract

Es wird eine Zentrifuge mit einem durch einen elektrischen Antriebsmotor (12) angetriebenen Rotor (10) vorgeschlagen, an dem zur Erfassung der Ist-Drehzahl äquidistant angeord­ nete Markierungen (13) vorgesehen sind, die durch einen gehäusefesten Sensor (16) abgetastet werden. Zur Aus­ wertung ist ein eine Regeleinrichtung zur Regelung der Drehzahl des Antriebsmotors enthaltendes Steuergerät (17) vorgesehen. Um neben der Drehzahl weitere rotor­ spezifische Daten automatisch zu erhalten, sind weitere, vom Sensor (16) abtastbare Code-Markierungen (15) am Rotor (10) vorgesehen. Hierdurch ist es möglich, auch bei einem Rotorwechsel jeweils wieder automatisch die zugeordneten Grenzwerte oder Funktionskennlinien vorzu­ geben, so daß Fehlbedienungen weitgehend ausgeschlossen sind. It becomes a centrifuge with an electric one Proposed motor (12) driven rotor (10) proposed on which is arranged equidistant to record the actual speed Nete markings (13) are provided by a housing-fixed sensor (16) can be scanned. To the end is a control device for regulating the Speed of the drive motor containing control unit (17) provided. To add more rotor besides the speed Obtaining specific data automatically is another from the sensor (16) scannable code markings (15) on Rotor (10) provided. This makes it possible, too each time the rotor is changed, the assigned limit values or functional characteristics give so that incorrect operation largely excluded are.
