Vibration Monitoring

Vibration Monitoring
VIBRA-series

With a Profound VIBRA system you can easily monitor vibrations, which may cause damage to buildings and sensitive equipment or cause nuisance to persons. Vibrations can be caused by traffic, pile driving, demolition work or blasting.

During each time interval the VIBRA measures, directly displays and records both the maximum vibration levels and the vibration frequencies in x-, y- and z-direction. In addition every hour a full measuring signal of the highest peak value(s) is recorded. The VIBRA’s digital signal processing guarantees measurements of a high quality and accuracy.

The Profound VIBRA–series comprises the VIBRA and the VIBRA+. The top of the line VIBRA+ has several special features, including integrated 3G/internet options, PC Trace Recorder, displacement measurements and automatic level- and calibration checks.

Depending on the chosen model, the system meets national and international standards, such as DIN 4150-2 and -3, BS 5228-2, BS 7385-2, SBR, SS 460 48 66/61, AS 2187.2 and is according to DIN 45669-1:2010.

Key advantages

  • Continuous and online vibration monitoring according to a large range of standards such as DIN 4150-2 and -3, BS 5228-2, BS 7385-2, SBR A and B,
    SS 460 48 61, blasting standards SS 460 48 66 and AS 2187.2 and is according to DIN 45669-1:2010.
  • Direct display of measured peak values in X, Y, Z at the project location
  • Real-time interpretation and verification of the vibration levels against ruling codes
  • Downloading data or uploading data without measurement interruption
  • Unattended vibration measuring for up to 28 days due to the high-tech, low power consumption electronic design in combination with software intelligence. System can also be connected to the mains
  • Wireless automatic data transfer via integrated GPRS/3G
  • Flexible use: direct SMS alarm, e-mail, FTP
  • Real-time data upload to any FTP server
  • Ring memory including ring buffer in FTP mode
  • Additional turnkey online monitoring service via vibramonitoring.eu
  • Direct SMS alarm communication up to 5 selected recipients
    including start/stop functionality
  • Frequency-dependent velocity alarm (smart alarm)
  • ‘Search Networks’ option in the VIBRA+ system. Find the provider
    with the best GPRS connection at the project location
  • Compact, robust field-computer that is very easy to operate.
  • Professional and fast (graphical) presentation of the monitoring results.

Operation

Setting up the system on site is easy: attach the 3-dimensional sensor to the structure to be monitored, switch on the system and start measuring. During measuring the VIBRA displays the current vibration values of the 3 directions including frequency, the maxima, besides date, time, remaining battery capacity, available memory.

The VIBRA can be left unattended to operate continuously for weeks.
The system is robust, lightweight, portable and battery-operated. At the same time, the system provides a fully continuous and automatic registration of the vibration peak values up to a month.

The characteristics of the different models VIBRA and the VIBRA+ are further outlined in the VIBRA features overview.

Data handling

Real-time monitoring and analysis
The VIBRA+ can be set up for wireless automatic data transfer via the integrated 3G modem to your PC. Data can also be continuously uploaded to any FTP server for real-time online monitoring. As an alternative Profound offers a turnkey online monitoring service via www.vibramonitoring.eu.

The VIBRA can also be connected to your PC via USB for data retrieval, even while measuring. With the PC software supplied together with the system, data are directly presented in graphs for detailed reporting. You also simply export data to a csv-file. With the PC Remote Control software it is possible to log in remotely to your VIBRA system.

Application

With a Profound VIBRA system, vibrations that are caused by traffic, pile driving, demolition work or blasting can be monitored continually and accurately. By recording the vibrations you can assess the risk of damage to buildings and sensitive equipment as well as the nuisance to people in an objective manner in accordance with the applicable guidelines

Academy

You or your colleagues have been working for some time with a vibration monitoring system of the VIBRA-series, but regulations and guidelines are adapted and the materials are developing continuously. Especially for users of the VIBRA or VIBRA+ system we have developed the refresher course “Vibration Monitoring & Analysis in accordance with vibration monitoring codes”.
