Machine and/or monitoring

A system for automatic on-line monitoring of the status of a machine and/or a process run on the machine, the system comprising:

• at least one sensor for measuring a plurality of parameters containing information about the status of the machine and/or the process run on the machine, wherein said sensor is configured to sense a plurality of parameters containing information about a mechanical condition of at least one moving part of the machine, wherein said machine has at least a rotating component and said at least one moving part is a bearing of said rotating component of said machine, and wherein said at least one sensor is mounted for sensing vibrations in said bearing and producing a corresponding vibration signal;
• measuring means for determining a loading of said machine by measuring at least one signal representing an operating condition of said machine and/or a parameter of a process run on said machine simultaneously with the sensing of said vibration signal;
• data storing means for storing said vibration signal data together with said simultaneously measured operating condition and/or parameter data;
• selecting means for selecting stored vibration signal data depending on values of stored simultaneously measured operating condition and/or process parameter data;
• further signal processing means for further signal processing of said selected vibration signal data for monitoring purposes;
• a database having a plurality of stored reference values for said measured parameters;
• means for extracting from said database the corresponding reference values according to a predetermined criterion;
• and a comparator for comparing said plurality of measured parameters with said plurality of corresponding reference values for determining the status of the machine and/or the process.
