Vibration Measurement

Vibration Measurement

Vibration measurement is an important factor in predictive maintenance. It is a tool for monitoring the condition of different types of production machinery. Vibration measurement is used on equipment that has rotating parts, for example, pumps, turbines and fans. It can detect their vibration levels and therefore assess their condition, thus helping you to be able to reduce unnecessary downtime and repairs.

With Kiwa Inspecta’s help you can monitor your equipment continuously, find reasons behind any deviations and defects as well as finding problems in components before they fail and cause further damage. A good vibration measurement survey can determine if the machinery is out of alignment or unbalanced, if the belts are worn or loose and if gear teeth are worn or chipped.

Vibration measurement is executed with an accelerometer and the frequencies used vary from 1 to 10 000 Hz. The electrical signal changes when the target vibrates and these changes are seen in the monitoring device. In interpreting the results expertise is needed, as all machines vibrate. However it’s powerful vibrations that show if a defect has become a problem. The collected and analyzed data reveals conditions such as defects in bearings, imbalance, shaft misalignment, wear in gears, and so on. The biggest advantages are gained when measurements are repeated on a regular basis so that the results can be compared.

We recommend remote monitoring systems for all other important (pump, fans, gearboxes etc) rotating machinery too. Certain vibration monitors with remote monitoring allows for reliable detection of early defects in machines without the need for a vibration expert to be on site. System reports change automatically via telecommunication systems to our expert at any time. This kind of remote monitoring system saves you time and money in the long run. Putting it briefly, we help to turn your maintenance from reactive to proactive.

Benefits of Vibration Measurement

  • Reduces unnecessary downtime, brings cost savings
  • Predicts machine failures
  • Assesses the condition of the machines that are critical to the process
  • Visualizes the defects as soon as they start occuring
  • Enables you to predict the remaining lifetime of the equipment
  • Helps you to plan repairs
