Vibration sensor and development kit can shake up industry 4.0
For industry 4.0 application, STMicroelectronics introduces a vibration sensor and supporting evaluation kit. The IIS3DWB vibration sensor and STEVAL-STWINKT1 multi-sensor evaluation kit are designed to accelerate development of condition-monitoring systems that boost productivity by inferring equipment maintenance needs. They operate on the principle of analyzing the sensed vibration data locally or in the cloud to help owners create strategies based on that data to maximise uptime, minimise servicing costs and avoid emergency repairs.
The IIS3DWB is a three-axis MEMS accelerometer optimised for industrial vibration sensing. The STEVAL-STWINKT1 kit simplifies prototyping and testing by integrating the IIS3DWB with additional sensors, a low-power microcontroller and algorithms for vibration processing, Bluetooth wireless module and USB connection. The kit is housed in a plastic enclosure with a battery and serves as a reference design.There is a high-speed data-logger and cloud-dashboard to collect, analyse and visualise the results.
The frequency response is tailored to be fully flat and with low noise up to 6kHz and then with a sharp cut off and high attenuation to remove frequency-aliasing concerns and to detect machine-related faults with accuracy and consistency.
“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,” said Alessandro Cremonesi, vice president of System Research and Applications, STMicroelectronics.
ST is already supplying the IIS3DWB to SPM Instrument of Sweden, for use in the company’s Airius wireless, battery-powered vibration sensor. Rikard Svärd, global sales director of SPM Instrument commented: “We chose IIS3DWB for its . . . combination of features, including three-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.”
The IIS3DWB vibration-sensing system-in-package (SiP) is in production now and available in a 14-lead plastic land grid array (LGA) package. The STEVAL-STWINKT1 is also available now.
