Vibration Monitoring: What kind of equipment is used?
Seismographs are instruments used to measure the amplitude, frequency and duration of vibrations caused by construction, engineering, and other equipment vibrations. A variety of vibration sources can be measured to determine the amplitude in velocity (inches/second) and the frequency (Hz) of the movement, typically in the soil close to a structure of concern. In a majority of cases, the vibration levels are measured to ensure that a particular structure of concern is not being damaged by the vibration source. The typical industrial seismograph measure 3 components of motion, longitudinal or parallel to (towards) the vibration source, transverse or perpendicular to the vibration source and vertical which is up and down. Depending on the vibration source, we may also want to measure air overpressure using a linear microphone.
