Operation-control device for operation and method for controlling operation of a disperser and disperser system comprising a disperser and a computer program product

An operation-control device adapted for controlling operation of a disperser, said disperser having a rotor unit for rotating in a liquid,

• the operation-control device comprising:
• an input unit for receiving, from external sensing devices, state-values of at least two different physical entities and/or operational states of the disperser associated to a dispersing process of the disperser;
• a functional-correlation storage unit configured to store at least one functional correlation model comprising one or more correlations of state-values of subsets of different physical entities and/or operational states of the disperser, wherein a given state-value of at least one of the subsets puts the state-value of at least another subset under a predetermined plausibility condition associated to a correlation of the functional correlation model;
• and
• a plausibility-checking unit connected to the input unit and to the functional-correlation storage unit and configured to determine a flag to the plausibility condition associated to the correlation of the state-values received and to provide a corresponding status signal.
