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.
The ADIS16229’s dynamic range, bandwidth, sample rate and
noise performance are well suited for a wide variety of machine
health and production equipment monitoring systems. This
devices also provides a number of wireless configuration
parameters enable a wide level of flexibility in managing the
trade-off between battery life and communication frequency.
The ADIS16000 SPI interface provides simple connectivity with
most embedded processor platforms and the SMA connector
interface enables the use of many different antennas. This
module supports up to six ADIS16229 devices at one time,
using a proprietary wireless protocol.
Both ADIS16000 and ADIS16229 modules are in in
47.0x37.6x22.6mm PCB structures, have an SMA connector for
simple antenna connection, have two mounting holes for simple
installation and support operation over a temperature range of -
40°C to +85°C. The ADIS16000 also includes a standard 1mm,
14-pin connector for connecting to an embedded processor
system. The ADIS16229 provides a lead structure that enables
simple connection with standard batteries.
