ANALOG DEVICES EVAL-CN0579-ARDZ

EVAL-CN0579-ARDZ is a condition-based monitoring (CbM) evaluation board that enables early detection and diagnosis of machine and system abnormalities. Identifying and isolating these issues creates opportunities for optimizing replacement part inventories, scheduling downtime for planned maintenance, and making run-time process adjustments that can extend the life of equipment. It is a 4-channel, high resolution, wide bandwidth, high dynamic range, IEPE-compatible interface data acquisition (DAQ) system that interfaces with IC piezoelectric (ICP®)/IEPE sensors. While most solutions that interface with piezoelectric sensors in the market are AC-coupled and lack DC and subhertz measurement capabilities, this solution is DC-coupled. By looking at the complete data set from an IEPE vibration sensor in the frequency domain, the type and source of a machine fault can be better predicted using the position, amplitude, and number of harmonics found in the fast Fourier transform spectrum.
