MICRO-VIBRATION

LABS/RESEARCH FACILITIES/HOSPITALS

Micro-vibration is very different from standard “vibration”. We are experts in both fields, however micro-vibration monitoring requires entirely different equipment and a different set of skills and understanding to interpret the data.

Micro-vibrations usually have the most detrimental impact in laboratory environments where sensitive equipment such as MRIs, electron microscopes, mass spectrometers, or NMRs are being used. This equipment requires isolation from internal and external movement of the floor and usually requires specific construction and installation guidelines. In these environments, floor vibrations down to 0.1 nanometer peak to peak, 1 micro-g RMS or 0.8 micro-in./s RMS, from 0.4 Hz to 4 kHz can be monitored continuously over long periods of time and are often monitored permanently. Longer term samples provide better resolution for diagnostics than a one-time site visit, and continuous monitoring will alert the interested parties to any unexpected new or increased vibration that would not have been detected otherwise.

We provide micro-vibration monitoring on site for both new construction and for existing facilities to determine the viability of equipment installation locations. It is better to guarantee that the laboratory environment is suitable for the equipment before it is moved or installed than after it is in use and producing faulty results or bad data.

We also work with architects and planners in the schematic design phase with feasibility baseline site surveys to achieve proper vibration isolation of ultra-sensitive equipment before installation, and provide conformance or follow-up testing. Our measurement systems are wireless and either send data to our cloud or collect data internally. Sound and vibration data can be coupled to video data if necessary. When building structures require dynamic analysis, we can provide Finite Element Analysis as well.
