CN0532 Circuit Note Analog Devices

Vibration monitoring is a common type of CbM measurement because changes in vibration trends are potentially indicative of wear or other failure modes. To measure vibration data, high bandwidth (10 kHz and more), ultralow noise (100 µg/√Hz or lower) piezoelectric sensors were historically used to satisfy these requirements.
