DK Sense sends automated SMS alerts when the plant operates outside defined parameters for a preset duration.

Currently configured for Delta Group:

  • Low Level Alarm notifications
  • High Level Alarm notifications
  • Alerts triggered only if abnormal conditions persist beyond preset time thresholds

This prevents nuisance alarms while ensuring critical issues are escalated promptly.

Even when managers are off-site, they receive immediate notification of abnormal plant conditions.

6️⃣ Bottleneck Identification & Throughput Optimisation

Through live trend analysis and historical data review, DK Sense helps identify:

  • Feed inconsistencies
  • Conveyor limitations
  • Crusher overload cycles
  • Idle gaps between material flow
  • Shift-based performance variations

This insight enables management to:

  • Remove bottlenecks
  • Improve material flow balance
  • Increase achievable throughput
  • Run plant safely at optimal capacity
