Unlike typical single measurement systems, the online VV sensor is capable to prevent failures and mitigate catastrophic damages.
The VV simultaneously monitors equipment for four categories of machine problems: impact, fatigue, friction and temperature.
| IMPACT | FATIGUE | FRICTION | TEMPERATURE | |
|---|---|---|---|---|
| Crashes |
Mechanical issues Assembly issues |
Friction Grinding |
Overheating | |
| Examples of failure conditions: |
Colliding blades Ingested object Struck by moving object Improper sequence timing |
Misalignment Unbalance Belt issues Loose footing Structural issues |
Failing bearing Rubbing impeller Dragging blade Cavitation |
Loss of lubrication Loss of coolant flow Electrical issues Excessive load Excessive rubbing |
| Sensor measurement: |
Maximum acceleration a-Peak |
Average velocity v-RMS | Average acceleration a-RMS | Temperature º C |
