Vibration Amplitude. The maximum amplitude or range of the vibration you are measuring determines the sensor range that you can use. If you attempt to measure vibration outside a sensor's range, it distorts or clips the response. Typically, accelerometers used to monitor high vibration levels have a lower sensitivity and lower mass. Sensitivity

The research results indicate that the test rig dynamic model can capture the vibration amplitude and main frequency characteristics well, especially for the vibration below 1000 Hz. For the wheelset-gearbox system without track excitation, its vibration energy is basically concentrated in the resonance region of test object.

The most common sensor used in vibration analysis is the accelerometer, however you may also find velocity transducers and displacement probes. In fact, accelerometers provide a voltage output whose amplitude is proportional to the acceleration of the vibration.

The frequency at which the vibration occurs indicates the type of fault. That is, certain types of faults "typically" occur at certain frequencies. By

The Urban.io Vibration Sensor samples acceleration every 10 minutes. Time domain samples are converted to speed, then converted to frequency domain.
