Manufacturers need to increase machine availability and reduce unscheduled downtime in order to respond to global competition, requiring techniques that will help to manage maintenance and maximise reliable production. Condition monitoring offers a predictive approach to plant maintenance, ensuring optimum asset performance while keeping downtime to a minimum.

The Smart Condition Monitoring (SCM) solution from Mitsubishi Electric provides an integrated approach to monitoring the condition of individual assets and enables a holistic approach to be taken to monitoring the asset health of the whole plant. Individual sensors provide both an in-built ‘traffic light’ warning indication at the machine, but at the same time plain text information from multiple sensors is transferred over Ethernet to the smart sensor controller for in-depth monitoring and more detailed analysis.

Operational benefits

Linking multiple sensors into the sensor control system enables the controller to analyse patterns of operation that are outside the norm, with a series of defined alarm conditions that provide alerts that attention is needed.

The SCM analysis provides detailed diagnostics, offers suggestions for where additional measurements should be taken, and provides maintenance staff more precise error identification with identifying the root case and even recommendations as to what rectification actions should be taken, with clear text messages presented to personnel. This information can be networked to higher-level systems for ongoing trend analysis across all of the assets around the plant.
