VIBRA-Series

With a Profound VIBRA you can easily monitor vibrations, which may cause damage to buildings and sensitive equipment. 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.

With a Profound VIBRA you can easily monitor vibrations, which may cause damage to buildings and sensitive equipment. 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.

Profound has developed 3 different models to meet the individual requirements of our clients. Independent of the chosen version of the VIBRA, it speaks for itself that the system is of national and international standards, such as the SBR2002, the DIN 4150 and the DIN 45669.

Main Characteristics • Fully continuous and automatic registration of the vibration peak values during a long period of time: velocity and frequency, acceleration in x-, y-, z-direction • 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 and the SBR 2002 • Real-time interpretation and verification of the vibration levels against ruling codes • Downloading while measuring • Unattended vibration measuring for weeks due to the high-tech, low power consumption electronic design in combination with software intelligence. • Compact, robust field-computer that is very easy to operate. • Professional and fast (graphical) presentation of the monitoring results. • The possibility to attach an external alarm beacon to the system. • Easy comparison of measuring results: more than one VIBRA can be installed at the same location and the units are easily synchronized.

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.

Interpretation: Once monitoring has been completed the VIBRA is connected via USB to a (portable) Windows computer for full analysis. Full Windows PC software is included.

Specific advantages of the VIBRA+ • Full compliance with DIN 4150 - part 2 and 3/SBR – part A, B including: o Simultaneous measurements o Dominant frequency determination with FFT method o Software processing o KBFT and KBFmax/veff,max • Smart alarm (frequency dependent alarm) • Automatic daily status and data e-mail via GPRS/internet without measurement interruption • E-mail alarm via GPRS/internet • Peak displacement recorded for each channel • Automatic level- and calibration checks • Continuous PC Trace Recorder
