The VV sensor is designed to prevent the primary categories of machine failure.

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.

Vibration monitoring methods:

  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
