Compact multi-axis MEMS vibration monitor provides exceptional low-noise performance and embedded analysis

BANGALORE, INDIA: Analog Devices Inc. (ADI) is continuing to help industrial equipment designers improve system performance and reduce maintenance costs through more efficient vibration detection and isolation with the introduction today of the MEMS-based ADIS16228 iSensor vibration monitor.

The fully integrated vibration analysis system features an embedded programmable processor that provides directional sensing and spectral analysis to identify and classify individual sources of vibration. This enables the earliest possible detection, identification, and isolation of vibration sources from equipment and bearing wear that otherwise can lead to operating errors and costly equipment downtime.

The noise performance of the ADIS16228 vibration monitor is specified at only 248 µg/ √Hz, across a dynamic range of ±18g, configurable to settings of 0 g to 1 g/5 g/10 g/20 g. By embedding these small vibration monitors, applications ranging from wind turbines to precision factory automation and assembly equipment will benefit from automatic vibration profiling.

“MEMS accelerometers are well suited for vibration monitoring, but are typically at a low level of integration. With decades of integrated sensor processing experience, Analog Devices transformed a MEMS accelerometer into a 3-axis vibration analyzer with programmable embedded processing,” said Bob Scannell, iSensor business development manager, MEMS/Sensors Group, Analog Devices. “For the first time, industrial equipment designers have a low noise, easy-to-use, affordable and complete vibration analyzer that is compact and directly embeddable.”

The ADIS16228 iSensor vibration monitor eliminates the complexity and risk of developing a vibration solution from discrete components and enables a much wider application base, by integrating the intelligence and analysis only found in bulky handheld monitors which required trained vibration analysts.

With the ADIS16228, developers have access to proven vibration sensing capability with frequency domain processing programmability and tuning that greatly improves the ability to isolate the vibration source quickly. The ADIS16228 is available in a 15 mm × 24 mm × 15 mm aluminum module with flanges, M2 machine screw holes, and a flexible connector that enables simple user interface and installation.
