Sound and Vibration Devices

Vibration is the mechanical oscillation of a machine or object about an axis. Measuring vibration, acceleration, and acoustic signals is crucial in a variety of industries. Vibration measurements and trends can be used as an indication of machine health, and accurately measuring vibration using an accelerometer or other vibration sensor can help predict machine failure and schedule maintenance.
