Condition Monitoring Solution for Machines and Plants

 Vibration Analysis

  Torque Measurement

The vibration specialist also checks out the machine when its condition worsens. The first signs appear with excessive vibration values, which are recorded during condition monitoring. The specialist uses high-performance analyzers, Instrument Calibration Tools and suitable methods to find the root-cause of the increased vibrations in order to remedy the problem as soon as possible.

Overview: Vibration analysis consists in listening inside the machine. Each component vibrates differently and generates a characteristic noise that leaves a typical fingerprint in the spectrum in the form of a linear pattern. If damage is present, the pattern stands out from the noise floor. This allows the specialist to recognize, for example, whether the problem comes from unbalance, misalignment or bearing damage. In addition to an accurate diagnosis it is generally also possible to determine whether urgent action is necessary or whether it can wait until the next scheduled servicing.

Benefit: The bottom line is that vibration analysis benefits both the operator and the maintenance technician:

  • Enables the identification of machine faults
  • Provides information on root causes
  • Localizes the affected components
  • Optimizes spare parts logistics
  • Allows early planning of maintenance measures

 Arrangement for torque measurement: Your aim is to enhance machine performance and throughput. Torque measurements can be used to determine the effective loads in the drive system and, for example, to check the function of the safety couplings.


Make machine load visible: Machine manufacturers select drive components such as gears, couplings, motors, converters and various Instrument Calibration Tools,  so as to ensure that the machines have the necessary torque available to them at the required operating speed. For cost reasons, increasingly lighter and smaller gears and couplings must transmit ever more power. This can lead to sudden, dangerous torsional vibration and even fatigue fractures.

Drive specialists know that after the second shaft fracture on identical machines – at the latest – it is time for torque measurements with strain gauges. The only way to measure static and dynamic loads over several weeks is by mechanical torque measurement at high frequency. Critical natural vibrations are also looked for at this time. Also possible are,
