Low Power Integrated MEMS-Based Devices Optimize Embedded Shock and Vibration Sensing for Industrial Applications

The need to accurately sense and record motion has become prevalent in many industrial applications. Properly tuned MEMS accelerometers can be used to detect both subtle and excessive vibration, as well as shock events. With high power efficiency and a small profile, they can also be embedded into nearly any piece of end equipment and much closer to the motion source.

Solution
ADI has integrated its industry-leading MEMS sensing technology with signal processing and embedded controllers to form complete programmable shock and vibration sensing and recording systems. The new low power ADIS16240 impact sensor and shock recorder monitors and captures shock events on three axes without requiring any external intervention. The ADIS16220 vibration sensor has a 22 kHz bandwidth response making it most suitable for capturing and recording vibration. It also contains an integrated averaging/decimating filter, which provides optimization for lower bandwidth applications. Both of these motion sensing devices have wide ranging applications—from improving predictive maintenance capability in industrial machinery to passive monitoring for abusive handling of either high value equipment or shipments. The tiny packages also contain data capture buffers and have been optimized for low power making them perfect for long-term passive monitoring. With programmable alarm settings and a simple SPI interface, designers can easily integrate the devices into existing systems as autonomous shock and vibration monitors.
