Unlike analog 4-20 mA sensors that measure overall vibration, digital vibration monitoring is based on accelerometer waveforms. This allows for independently configurable bands for multi-targeted fault detection based on full vibration spectrum data and simplified data for process monitoring.
TAKEAWAY: Digital vibration monitoring solutions bridge the gap between vibration analysis and process monitoring, diagnosing developing faults and providing 24/7 online monitoring as complementary approaches to condition-based maintenance.
