MEMS vibration monitor provides ‘exceptional’ low noise performance

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 is said to enable 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 rated at 248µg/ vHz, across a dynamic range of ±18g. This is configurable to settings of 0g to 1 g/5 g/10 g/20 g. By embedding these small vibration monitors, ADI says applications ranging from wind turbines to precision factory automation and assembly equipment can benefit from automatic vibration profiling. "For the first time, industrial equipment designers have a low noise, easy to use, affordable and complete vibration analyser that is compact and directly embeddable," said Bob Scannell, iSensor business development manager, MEMS/Sensors Group, ADI. According to Scannell, the vibration monitor eliminates the complexity and risk of developing a vibration solution from discrete components and enables a wider application base. The device is available in a 15 × 24 × 15mm aluminium module with flanges, M2 machine screw holes and a flexible connector that is optimised to enable simple user interface and installation.
