The ADcmXL1021-1 vibration sensor from Analog Devices is now being shipped by distributor Mouser Electronics.

Based on Analog Devices' microelectromechanical system (MEMS) sensor technology, the ADcmXL1021-1 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.

It is a single z-axis vibration monitoring subsystem designed to simplify the development of smart sensor nodes in condition-based monitoring (CBM) systems.

The device incorporates a wide-bandwidth, low-noise MEMS accelerometer plus 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.

Signal processing includes high-speed data sampling (220 kSPS), 4096 time sample record lengths, filtering, windowing, fast Fourier transform (FFT), user-configurable spectral or time statistic alarms, and error flags.

The sensor uses an ADXL1002 MEMS accelerometer with ultra-low noise density (26 µg/√Hz) to support excellent resolution.

With a wide bandwidth of DC to 10 kHz, the device enables tracking of key vibration signatures on many machine-based platforms.

It offers a high operating input range of ±50 g, making it suitable for vibration measurements in high-bandwidth Industrial Internet of Things (IIoT) and Industry 4.0 applications such as vibration analysis systems that monitor and diagnose machine or system health, as well as safety shutoff sensing.

Mouser also stocks the EVAL-ADCM-1 evaluation kit, which includes the ADcmXL1021-1 module, a breakout board, an ADcmXL interface board, a Cypress Semiconductor EZ-USBFX3 board, and necessary cables.

Engineers can connect the kit to a PC to access evaluation software for effortless configuration of the module, register setup, data display, and data logging.

The sensor is now available from Mouser Electronics in north America, the EMEA region and Asia/Pacific.
