Analog Devices is continuing to help industrial equipment designers improve system performance and reduce maintenance costs through more efficient vibration detection and isolation with the introduction 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 is specified at only 248 μg/Hz, across a dynamic range of ±18 G, 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.
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 device is available in a 15 x 24 x 15 mm aluminium module with flanges, M2 machine screw holes, and a flexible connector that enables simple user interface and installation.
The tri-axial, digital vibration monitor’s SPI and data buffer structure provide easy access to sensor data. The IC 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.
