Analog Devices Press Release - September 26, 2011

Analog Devices’ Compact Multi-Axis MEMS Vibration Monitor Provides Exceptional Low-Noise Performance and Embedded Analysis Visit Analog Devices

ADIS16228 iSensor® vibration monitorNORWOOD, Mass.--(BUSINESS WIRE)-- 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.

More About the ADIS16228 iSensor Digital Vibration Monitor
The ADIS16228 iSensor tri-axial, digital vibration monitor combines industry-leading iMEMS® sensor technology with ADI’s data conversion and sensor signal processing technologies with convenient data capture and an SPI (serial peripheral interface). The SPI and data buffer structure provide easy access to sensor data. The ADIS16228 samples, processes and stores x, y and z acceleration data with FFT (fast Fourier transform) processing including time stamp. The programmable digital filter offers low-pass configuration options, and an internal clock drives the data sampling system during a data capture event, which eliminates the need for an external clock source. The data capture function has three different modes that will accommodate the needs of many different applications. The ADIS16228 also offers an integrated digital temperature sensor and digital power-supply measurements, as well as a digital self-test feature that enables reliable embedded operation within the targeted applications. The extended operating temperature range for the device is −40°C to +125°C. For more information, download the data sheet.

ADIS16228 Key High-Performance Features and Benefits:
  • Embedded frequency domain processing, 512-point, real-value FFT algorithms and on-board storage identify and classify individual sources of vibration, monitor changes over time and react to programmable threshold levels.
  • Low-noise performance specified at 248 µg/ √Hz greatly improves the ability to discern unwanted vibration from normal operation.
  • Programmable spectral alarm bands allow analysis of the full frequency spectrum with the configuration of 6 bands, Alarm1 (warning threshold) and Alarm2 (fault threshold) for earlier and more accurate fault detection.
  • On-chip data capture function has three modes that offer several options to meet the needs of many different applications.
  • User configurable multi-mode operation (including real-time-capture mode) allows more accurate assessment of even subtle vibration profile changes.
