The ADcmXL3021 triaxial vibration sensor from Analog Devices is in stock at Mouser Electronics. Based on Analog Devices’ micromechanical (MEMS) sensor technology, the module is a complete sensing system that monitors for early indications of possible machine fatigue and failure specifically in industrial and transportation equipment to help reduce repair costs and maintain a high level of productivity.

The module is a triaxial (3-axis) vibration monitoring subsystem.

It incorporates Analog Devices’ high-performance MEMS sensors with an analogue-to-digital converter (ADC), high-performance signal processing, data buffers, record storage, and a user interface that easily works with most embedded processors.

Three ADXL1002 MEMS accelerometers with ultra-low noise density (25µg/√Hz) support excellent resolution.

Designed with a wide bandwidth, the device enables tracking of key vibration signatures on many machine-based platforms.

With a high operating input range of ±50g, the ADcmXL3021 is suitable for vibration measurements in high-bandwidth applications such as vibration analysis systems that monitor and diagnose machine or system health.

The module helps simplify the development of condition-based monitoring (CBM) systems for Industrial Internet of Things (IIoT) and Industry 4.0 applications, including instrumentation, diagnostics, and safety shutoff sensing.
