Measuring of vibrations

When undesirably large vibrations in machine occur, quick action is needed - especially in modern production facilities with high hourly rates. The first step is always the metrological diagnosis.

When undesirably large vibrations in machine occur, quick action is needed - especially in modern production facilities with high hourly rates. The first step is always the metrological diagnosis.

For this purpose we offer you our expertise in various diagnostic procedures:

  • operating vibration analysis in the production
  • Machine high runs with waterfall
  • ' Polluter Pays ' analysis by synchronized averaging
  • Identification of resonance frequencies, experimental modal
  • Analysis of rolling bearing diagnosis.

On the basis of the diagnosis we discuss with you specific approaches and measures to address the vibration issues.

A decisive factor for successful machine diagnostics is, in addition to the know-how of our engineers, the available measuring technology. In particular, Wölfel uses the following mobile technology:

  • Data acquisition and analysis software for machine diagnostics, eg. MEDA, developed by Wölfel
  • Signal detection systems (up to> 40 channels, real-time synchronous sampling, anti-aliasing filter, highest sampling rates)
  • Acceleration measurement technology
  • Highly sensitive, special seismic sensors
  • Special sensors (rotary acceleration sensors, displacement transducers, etc.)
  • Laser-Scanning-Vibrometer
  • 3D-digitizer unit for geometric measurement of structure and measuring points
  • Impact hammers with force sensors in different sizes
  • Mobile shakers (Shaker of different performance classes)
