Digital Triaxial Vibration Sensor with FFT Analysis and Storage
The ADIS16228 iSensor® is a complete vibration sensing system that combines triaxial 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 for each axis, along with FFT averaging, which reduces the noise floor variation for finer resolution. The 14-record FFT storage system offers users the ability to track changes over time and to capture FFTs with multiple decimation filter settings.
The 20.48 kSPS sample rate and 5 kHz flat frequency band provide a frequency response that is suitable for many machine health applications. The aluminum core provides excellent mechanical coupling to the MEMS acceleration sensors. An internal clock drives the data sampling and signal processing system during all operations, which eliminates the need for an external clock source. The data capture function has three modes that offer several options to meet the needs of many different applications. In addition, real-time mode provides direct access to streaming data on one axis. The SPI and data buffer structure provide convenient access to data output. The ADIS16228 also offers a digital temperature sensor and digital power supply measurements.
The ADIS16228 is available in a 15 mm × 24 mm × 15 mm module with flanges, machine screw holes (M2 or 2-56), and a flexible connector that enables simple user interface and installation. It has an extended operating temperature range of −40°C to +125°C.
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADIS16228/PCBZ is a "breakout board," which provides (1) ADIS16228CMLZ and (1) interface PCB to simplify the process of "prototyping" during the early stages of system design and evaluation. The ADIS16228CMLZ is a fully-integrated, vibration measurement/analysis system, which provides a serial peripheral interface (SPI) for all digital communications. It provides a flexible connector interface, with a 15-pin, edge-terminated connection, which minimizes board space, but does not support standard ribbon cable connections. The interface PCB provides access to the ADIS16228CMLZ, using a dual-row, 16-pin connector, which supports standard ribbon cable systems and hand-soldering connection techniques. The interface PCB also provides two sets of mounting holes: one set of holes for attaching the ADIS16228CMLZ to the interface PCB and another set of holes for mounting the interface board to the system’s frame. The first set of holes line up with the ADIS16228CMLZ's mounting holes and are pre-tapped for use with M2x0.4mm machine screws. The second set of holes are support M2 machine screws and line up with M2x0.4mm, pre-tapped holes on the ADISUSB evaluation system board.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
