Low-cost vibrations-monitorering i industriapplikationer

ST Microelectronics lancerer MEMS-baseret vibrations-sensor, der er optimeret til industriel monitorering (in english).

STMicroelectronics (ST) is aiming at the next generation of Industry 4.0 applications with a new vibration-sensing solution optimized to enable smart maintenance of factory equipment.

ST’s IIS3DWB vibration sensor and supporting STEVAL-STWINKT1 multi-sensor evaluation kit accelerate development of condition-monitoring systems that boost productivity by inferring equipment maintenance needs. Analyzing the sensed vibration data locally or in the cloud helps owners create strategies that maximize uptime, minimize servicing costs, and avoid emergency repairs.


The IIS3DWB is a 3-axis MEMS1 accelerometer optimized for industrial vibration sensing. The STEVAL-STWINKT1 simplifies prototyping and testing by integrating the IIS3DWB with additional sensors, an ultra-low-power microcontroller and algorithms for vibration processing, Bluetooth wireless module, and USB connection.
Housed in a plastic enclosure with a battery, the kit is ready to begin application development and presents a convenient reference design. High-speed data-logger and cloud-dashboard utilities are included to help collect, analyze, and visualize the results.

- Machine-condition monitoring is central to industrial digital transformation, bringing the power to enhance manufacturing performance and safety while enabling new services and business models, says Alessandro Cremonesi, Vice President of System Research and Applications, STMicroelectronics.

- Our vibration sensor and IIoT multi-sensor development kit and reference design are the best performing and most affordable solutions in the market today, enabling high-performance and cost-effective plug-and-play industrial sensing. 

ST is already supplying the IIS3DWB to IIoT technology innovator SPM Instrument of Sweden, for use in the Company’s AIRIUS wireless, battery-powered vibration sensor. Rikard Svärd, Global Sales Director of SPM Instrument explains:

- We chose IIS3DWB for its unique combination of features, including 3-axis sensing, wide bandwidth, and low noise in a low-power, digital device, which helped us achieve the performance, design-cycle time and cost targets we set for AIRIUS.
