GENERAL DESCRIPTION

The ADIS16000 and ADIS16229 enable creation of a simple wireless vibration-sensing network for a wide variety of industrial-equipment applications. . The ADIS16000 provides the gateway function, which manages the network, while the ADIS16229 provides the remote sensing function. The ADIS16229 iSesnor is a complete wireless vibration sensor node that combines dual-axis acceleration sensing with advanced time domain and frequency domain signal processing. Time domain signal processing includes a programmable decimation filter and selectable windowing function. Frequency domain processing includes a 512-point, real-valued FFT, FFT magnitude averaging, and programmable spectral alarms. The FFT record storage system offers users the ability to track changes over time and capture FFTs with multiple decimation filter settings.
