  • Method and device for imbalance detection
    Patent number: 11585718
    Abstract: A device (10) and method for sensor diagnostic monitoring and detection of an imbalance of a rotating machine (1) has steps of (a) detecting acceleration signals (Sb) of the housing (2) or of a non-rotating component of the rotating machine (1) by a sensor (20); (b) detecting signals (Sd) for the determination of the rotation speed of the rotating machine (1) by a second sensor; and (c) supplying and evaluating of sensor signals (Sb, Sd) by an evaluation unit (40, 50, 60). An acceleration component that is acquired occurs with the rotation speed of the rotating machine. This component is compared with a predetermined limit value.
