Analog Devices Inc. ADXL1003Z Evaluation Board
The ADXL1003 is a low-noise, wide bandwidth accelerometer that is ideal for condition monitoring and predictive maintenance in industrial applications, and it’s nothing like the accelerometer you will find in a smartphone or other consumer electronics.
A typical smartphone accelerometer has a range of ±16g, 2kHz bandwidth, and 120µg√Hz noise density. That’s fine for orientation detection, motion and activity tracking, and things of that nature. Contrast that with the ADXL1003, which has a measurement range of ±200g, 15kHz bandwidth, and 45µg√Hz noise density.
The combination of wide bandwidth and ultra-low noise density enables measuring the vibration of small components, such as bearings, while the ±200g range provides the dynamic range necessary for use in applications such as HVAC or industrial machinery. This makes the ADXL1003Z suitable for vibration measurements, detecting failing bearings, motor misalignment or imbalance, acoustic emissions, and other applications.
The device provides a ratiometric analog output and operates from a single 3.0V to 5.25V supply for ease of implementation. A typical current draw is just 1.0mA, allowing it to be used in battery-powered wireless sensor nodes, and it has integrated signal conditioning that enables full electromechanical self-test as well as overrange detection and indication. The device is packaged in a 32-lead 5mm x 5mm x 1.8mm LFCSP, with a -40°C to +125°C operating temperature range.
The ADXL1003Z evaluation board has an extra thick 0.8” x 0.8” PCB with screw holes for direct mounting to a mechanical shaker so it can be quickly evaluated. The board includes an RC low-pass filter, and the components can be replaced to set the bandwidth as needed for the intended application.
