Site Survey Measurement & Analysis
- Floor vibration measurement and analysis using micro seismic accelerometer: amplitude and frequency contents, narrow band power spectrum, 1/3 octave power spectrum, pass/fail analysis based on instrument specification.
- Vibration analysis based on instrument specification in velocity (micro meter per second) or displacement (micro meter). In addition, pass/fail analysis based on generic VC-Curves or any other standardized specification is possible.
- Long term (multi-hours) logging of signal under analysis (signal can be vibration, sound or electromagnetic field) with complete post-processing analysis (narrow band, 1/3 Octave, waterfall, capture events of crossing set values criterion, statistic analysis,…)
- Sound mapping (3D) to visualize the location of sound generating sources
- EMI mapping (3D) to localize the EMI induced sources (instruments, cable lines, ground loops)
- Frequency response function (like transmissibility) to evaluate the achieved attenuation factor by for example Active vibration isolation, or EMI canceling system. This test requires two or more sensors and multi-channels to capture and analyze signals simultaneously.
Site Monitoring & Site Assessments
- Vibration, noise and magnetic field monitoring for industry, construction and environmental needs.
- Pass/fail assessments against either manufacturer generated specifications or generic international recognized standards/criteria (VC lines, NC curves)
- Personal exposure / risk to strong (AC,DC) magnetic field assessment
- Micro-vibration monitoring is needed to protect a sensitive facility for example, a sensitive laboratory from construction activities. Vibration monitoring provides both real-time protection against high vibration levels as well as historical data to help assess whether damage was due to adjacent jobsites.
- Test planning, execution, data analysis and concise report incl. clear conclusions and recommendations in order to address existing relevant site issues and how to mitigate (cost) effectively within predefined constrains (time, costs and performance)
- The plan may consist one or more sources causing issues differently (e.g. construction vibration, footfall or neighboring equipments).
- Providing mitigation measures to improve the environmental condition meeting the tool requirements
