GENERAL DESCRIPTION
The ADcmXL1021-1 is a complete vibration sensing system that combines high performance vibration sensing (using a micro-electromechanical systems (MEMS) accelerometer) with a variety of signal processing functions to simplify the development of smart sensor nodes in condition-based monitoring (CBM) systems. The typical ultralow noise density (26 μg/√Hz) in the MEMS accelerometers supports excellent resolution. The wide bandwidth (dc to 10 kHz within 3 dB flatness) enables tracking of key vibration signatures on many machine platforms.
