    Spectra Tech employes sophisticated equipment and software to measurement and evaluate the human hand-arm or whole body vibration exposure experienced by workers (expressed in terms of acceleration, velocity, displacement). We can also provide assistance in designing solutions to reduce excessive vibration.

    • Units of vibration: The units of vibration depend on the vibrational parameter, as follows: acceleration, measured in g or [m/s2] velocity, measured in [m/s] displacement, measured in [m].
    • Vibration testing requires the use of a contact pickup, known as an accelerometer.
    • Test readings are usually taken in the three geometric axes: x, y, z, to determine the direction and degree of motion.
    • Spectra Tech uses the latest FFT analysis technology to diagnose vibration. Please see additional information at Detailed Specifications
    • Our system is capable of logging vibration data, and can precisely identify vibration and harmonics over a frequency range of 0.05 Hz to 20,000 Hz, with up to 6400 lines of resolution.
    • Our system can detect vibration as low as 0.0001 m/s2 acceleration in the lowest frequency range of 0.5 Hz to 100 Hz with extremely high accuracy.
    • The system is therefore suited to even the most demanding vibration tests, such as testing of worker's hand-arm vibration exposure while operating moving equipment (e.g., earth movers, fork lifts, etc. :
    • Plot / Print Test Results: We can provide documentation of test results by plotting / printing the test values on paper, and / or provide the reslts in PDF format.

    EXPERT / WITNESS TESTIMONY SERVICES ARE AVAILABLE TO PRESENT THE RESULTS OF TESTING AT A WORKERS COMP HEARING, OR IN A COURT CASE.
