Digital MEMS Vibration Sensor with Embedded RF Transceiver
The ADIS16229 iSensor® 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 fast Fourier transform (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.
The dynamic range, bandwidth, sample rate, and noise perfor-mance of the ADIS16229 are well suited for a wide variety of machine health and production equipment monitoring systems. This device also provides a number of wireless configuration parameters, enabling a wide level of flexibility in managing the trade-off between battery life and communication frequency.
The ADIS16000 serial peripheral interface (SPI) provides simple connectivity with most embedded processor platforms, and the SMA connector interface enables the use of many different anten-nas. This module supports up to six ADIS16229 devices at one time, using a proprietary wireless protocol.
The ADIS16000 module is available in a 37.8 mm × 22.8 mm × 8.8 mm multichip chip module laminate (MCML) structure, and the ADIS16229 is available in a 37.8 mm × 22.8 mm × 13.5 mm MCML structure. Both have an SMA connector for simple antenna connection, have two mounting holes for simple installation, and support operation over a −40°C to +85°C temperature range. The ADIS16000 also includes a standard 1 mm, 14-pin connector for connecting to an embedded processor system. The ADIS16229 provides a lead structure that enables simple connection with battery leads.
