Digital MEMS Vibration Sensor with Embedded RF Transceiver Data Sheet ADIS16000/ADIS16229 FEATURES GENERAL DESCRIPTION Wireless vibration system, 902.5 MHz to 927.5 MHz The ADIS16000 and ADIS16229 enable the creation of a simple Clear channel assessment and packet collision avoidance wireless vibration sensing network for a wide variety of industrial Error detection and correction in radio frequency (RF) equipment applications. The ADIS16000 provides the gateway protocol function, which manages the network, while the ADIS16229 Programmable RF output power provides the remote sensing function. Gateway node (ADIS16000) The ADIS16229 iSensor is a complete wireless vibration sensor SPI to RF function node that combines dual axis acceleration sensing with advanced Manage up to 6 sensor nodes time domain and frequency domain signal processing. Time Sensor node (ADIS16229) domain signal processing includes a programmable decimation Dual axis, 18 g MEMS accelerometer filter and selectable windowing function. Frequency domain 5.5 kHz sensor resonant frequency processing includes a 512-point, real valued fast Fourier transform Digital FFT range settings: 1 g, 5 g, 10 g, and 20 g (FFT) FFT magnitude averaging and programmable spectral Sample rate up to 20 kSPS alarms. The FFT record storage system offers users the ability to Programmable wake-up capture, update cycle times track changes over time and capture FFTs with multiple 512-point, real valued FFT decimation filter settings. Rectangular, Hanning, and flat top window options The dynamic range, bandwidth, sample rate, and noise perfor- Programmable decimation filter, 11 rate settings mance of the ADIS16229 are well suited for a wide variety of Multirecord capture for selected filter settings machine health and production equipment monitoring systems. Manual capture mode for time domain data collection This device also provides a number of wireless configuration Programmable FFT averaging of up to 255 averages parameters, enabling a wide level of flexibility in managing the Record storage: 14 FFT records on two axes (x and y) trade-off between battery life and communication frequency. Programmable alarms, 6 spectral bands, 2 levels Adjustable response delay to reduce false alarms The ADIS16000 serial peripheral interface (SPI) provides simple Internal self-test with status flags connectivity with most embedded processor platforms, and the Digital temperature and power supply measurements SMA connector interface enables the use of many different anten- Identification registers: serial number, device ID, user ID nas. This module supports up to six ADIS16229 devices at one 37.8 mm 22.8 mm 8.8 mm MCML package (ADIS16000) time, using a proprietary wireless protocol. 37.8 mm 22.8 mm 13.5 mm MCML package (ADIS16229) The ADIS16000 module is available in a 37.8 mm 22.8 mm Single-supply operation: 3.0 V to 3.6 V 8.8 mm multichip chip module laminate (MCML) structure, and Operating temperature range of 40C to +85C the ADIS16229 is available in a 37.8 mm 22.8 mm 13.5 mm APPLICATIONS MCML structure. Both have an SMA connector for simple antenna connection, have two mounting holes for simple installation, and Vibration analysis support operation over a 40C to +85C temperature range. Condition monitoring The ADIS16000 also includes a standard 1 mm, 14-pin connector Machine health for connecting to an embedded processor system. The ADIS16229 Instrumentation and diagnostics provides a lead structure that enables simple connection with Safety shutoff sensing battery leads.
