The sensors record the parameters of the industrial gear unit and forward these to the DriveRadar^® EdgeProcessingUnit (EPU). The package of sensors comprises 2 × acceleration sensors, 1 × oil temperature sensor, 1 × ultrasound sensor, 1 × speed sensor and 1 × DriveRadar^® EdgeProcessingUnit.

The sensors capture the following data:

• Operating hours
• Input speed and direction of rotation
• Vibration behavior of rolling bearings and gearing
• Oil level
• Oil temperature
• Oil viscosity
• Electronics temperature
• Ambient temperature
• Additional sensors can be connected

The DriveRadar^® EdgeProcessingUnit records all sensor data and transmits the collated measured values to the SEW-EURODRIVE data centers (certified in line with ISO/IEC 27001). The data is transmitted encrypted and at short intervals.

The raw data that has been collected is analyzed, interpreted and prepared in the SEW-EURODRIVE data centers:

• Vibration analysis at a constant and variable speed:
  • Condition of individual bearings and their components (outer ring, inner ring, rolling elements)
  • Condition of individual gearings (local gearing damage, circumferential gearing damage/wear)
• Forecast of remaining service life for rolling bearings and gearing:
  Monitoring of statistical failure probability as a predictive addition to vibration analysis
• Oil viscosity calculation
  based on the oil temperature recorded and the oil grade used
• Forecast for the next oil change:
  Prediction of the next oil change due based on oil condition calculated according to use
• Forecast of oil level:
  Prediction of the time until a critical oil level is reached due to a decrease or increase in the fill level (due to e.g. oil loss, oil contamination)
• Establishment of operating hours and idling times

The visualization in the DriveRadar^® IoT Suite allows you to see the current condition of the gear unit and its components at a glance:
This provides your basis for intelligent predictive maintenance.

• Depending on the measured value, the limit values stored in the system are either taken from your specifications, adopted from the gear unit selection process or generated by the self-learning system itself within the first few months of operation.
• The system informs you when a limit value is exceeded and also provides direct recommended actions for solving your problem.
• You can request the appropriate services for your industrial gear units in the web application at any time or immediately after a system notification.

Using an OPC UA interface as standard also means measurement data and condition information can be incorporated directly into your customer system. If the traffic light displayed changes to amber or red ("Overall Health Status"), this tells you when you should take a look at your DriveRadar^® IoT Suite.

Device list

The device list provides you with an overview of your industrial gear units. You can use filters and a grouping function to configure the view as you wish. A traffic light system simplifies continuous monitoring and ensures the user the transparency required in terms of gear unit condition, doing so in an intuitive way and at all times.

Overview of measured values and forecasts

Thanks to the visualization of condition and forecast values, you can see at a glance (everything is shown on one page) which measured values are OK or whether there are failures present.

• Compact overview of all relevant measured variables
• Vibration analysis and location of components
• Failure probability forecast for rolling bearings and gearing
• Oil level and oil change forecast
• Rapid access to contact and services

Detailed view and recommended actions

All historical data for a measured value is visualized in the detailed view. In the event of warnings and errors, you have the option of jumping straight to the time at which the incident was triggered.

• The recommended actions displayed help you rapidly eliminate the fault.
• If necessary, SEW-EURODRIVE can be easily contacted to request the appropriate services.
• An export function is provided for individual further processing of the displayed data.
