Reporting Vibration Compliance

Example of a vibration compliance report generated by Noise SentinelExample of a vibration compliance report generated by Noise SentinelCommon throughout the Noise Sentinel solution suites is the ability to produce graphical and tabular reports showing actual measured data against compliance limits. Vibration compliance reports form part of the Noise Sentinel output file in conjunction with noise data, system performance (data completeness) and system setup parameters.

Two types of vibration data are recorded:

  • Vibration period showing continuous periodic vibration
  • Vibration alerts including data from each exceedance

The vibration period may be set to record continuously from every 15 minutes to every hour. As with noise, the periodic data is summarised to show the maximum level daily and for daytime, evening and nighttime periods. The dominant zero crossing frequency of the vibration peak is shown and colour-coded according to one of three user-defined frequency bands. This enables any issues to be seen at a glance. It is typically high-level, low-frequency vibration which causes the most concern.

Fig. 4 shows a typical Noise Sentinel Alert Data report. This contains all the information provided for each vibration alert in the Real-time Control application, including any comments entered at the time of the alert. The report provides a complete record of vibration exceedances throughout the measurement.
