Vibra remote vibration monitoring for buildings

Profound VIBRA-series (VIB.00100/..110/..120/..130)
With the Profound VIBRA you can easily monitor vibrations, which may cause damage to buildings and sensitive equipment.
The robust aluminium housing is IP65 watertight. The system is easily portable, lightweight and battery-operated which allows for up to 4 weeks of continuous and undisturbed operation.
The Profound VIBRA-series comprises the VIBRA, the VIBRA-sbr and the VIBRA+. The specific characteristics of each system are further outlined in the VIBRA features list.
Depending on the chosen version of the VIBRA, the system is of national and international standards, such as the DIN 4150, the DIN 45669 and SBR.
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. While measuring the VIBRA displays date, time, time interval and the current vibration values including frequency in all 3 directions. In advance an alarm level can be set.
The remaining battery capacity and available memory are permanently shown on the display. During measuring it is also possible to view maximum vibration levels.
For full interpretation options the VIBRA is connected via USB to a Windows PC.

Main advantages for the Vibra remote vibration monitoring

Main characteristics VIBRA-series
 Fully continuous and automatic registration of the vibration peak values during a long period of time.
 The VIBRA-series is in accordance with national and international standards ‘Vibration in buildings’ – Effects on structures’ and ‘Effects on persons in buildings’, such as the DIN 4150 – part 2 and 3, DIN 45669.
 Real-time interpretation and verification of the vibration levels against ruling codes.
 Unattended vibration measuring for weeks due to the high-tech, low power consumption electronic design in combination with software intelligence.
 Compact, robust field-unit, which is very easy to operate.
 Professional and fast (graphical) presentation of the monitoring results.
 Adjustable alarm for velocity (mm/s).
 The option to connect an external (wireless) alarm beacon to the system.
 Includes VIBRA PC remote control. Remote log in to your VIBRA system if the system is connected via USB to a PC in the field.
 Easy comparison of measuring results: more than one VIBRA can be installed at the same location and the units are automatically synchronized in time.
Specific advantages of the VIBRA+
 Full compliance with DIN 4150 – part 2, 3 and SBR – part A, B including:
 Simultaneous measurements
 Dominant frequency determination with FFT method
 Software processing
 KBFT and KBFmax/veff,max
 Smart alarm (frequency dependent alarm on velocity according to DIN 4150)
 Alarm on acceleration (m/s2) or displacement (mm)
 Daily status and data via GPRS/internet
 Alarm via GPRS/internet
 Peak displacement recorded for each channel
 Automatic level- and calibration checks
 VIBRA PC Trace Recorder (for continuous trace time/velocity trace recording)

Vibra Geophone specifications

vibra geophone

Profound VIBRA geophone (VIB.00300)
The Profound geophone for the VIBRA range has been designed for high-performance vibration monitoring.

Advanced mounting
The ball joint in combination with the wall bracket facilitates precise orientation of the geophone in the correct x-, y- or z-direction, as well as enabling fine tuning of the vial.

Digital ID
The geophone has an electronic datasheet, whichvalso includes the serial number. Therefore, the source of measurement data can always be traced.

High-performance
Besides continuously monitoring the x-, y- and zdirection, the VIBRA also automatically corrects the measurement data for the individual sensitivity of each geophone channel. This guarantees high-quality measurements and performance.

VIBRA+
The VIBRA geophone in combination with the VIBRA+ offers the following extras:
ƒDetection of the geophone’s inclination,assuring that measurements are carried out with a correctly positioned geophone.
Based on data from the electronic datasheet,the VIBRA+ not only corrects the sensitivity, but also the resonance frequency and the quality factor with the help of digital correction filters.

More information about the VIBRA range can be found in the technical specifications.

Vibra Geophone Cone

Profound VIBRA geophone cone (VIB.00350)
The Profound geophone cone for the VIBRA range has been designed for high-performance ground vibration monitoring, measuring dynamic soil parameters. Installation of the geophone cone with standard cone penetration rods can be done by pushing it to the desired depth. When the desired depth has been reached, the rod is slightly retracted to minimise the vibration influence of the penetration rods.

Digital ID
The geophone cone has an electronic datasheet including the serial number. Therefore, the source of measurement data can always be traced.

High-performance
Besides continuously monitoring the x-, y- and zdirection, the VIBRA also automatically corrects the measurement data for the individual sensitivity of each geophone channel. This guarantees high-quality measurements and performance.

VIBRA+
The VIBRA geophone cone in combination with the VIBRA+ offers the following extras:
ƒ Detection of the geophone’s inclination, assuring that measurements are carried out with a correctly positioned geophone.
ƒ Based on data from the electronic datasheet, the VIBRA+ not only corrects the sensitivity, but also the resonance frequency and the quality factor with the help of digital correction filters.

Profound Vibra wireless alarm beacon (VIB.00407)

The VIBRA wireless alarm beacon is a rechargeable battery powered portable alarm that provides a visible alarm signal for a vibration monitoring system from the VIBRA-series.
After starting a measurement and upon exceeding a preset alarm threshold, the VIBRA system will automatically show an alarm text on the display.
Simultaneously the VIBRA system transmits a wireless alarm signal to the alarm beacon.
The high intensity LED’s of the alarm beacon effectively notify personnel of an exceeded vibration threshold.

Flexible use
The VIBRA wireless alarm beacon will receive alarm signals from all VIBRA systems within range, but can also be programmed to solely receive alarm signals from specifically linked VIBRA systems. Several beacons can also be linked to one VIBRA system.
Due to the wireless design and the integrated mounting options the beacon can easily be placed at clearly visible locations.
If another alarm device is required, the internal relay of the VIBRA wireless alarm beacon offers a flexible opportunity to link to other alarm devices.

Long operating life
The internal battery guarantees a long operating life. To indicate that the battery needs to be charged, the beacon will give a clearly visible red signal.
