Analog Devices Inc. IEPE Data Acquisition Board (EVAL-CN0540-ARDZ)

Analog Devices Inc. IEPE Data Acquisition Board (EVAL-CN0540-ARDZ) is a high-resolution, wide-bandwidth, high-dynamic-range Data Acquisition (DAQ) system that interfaces with the Integrated Electronics Piezoelectric (ICP®/IEPE) sensors. The EVAL-CN0540-ARDZ is designed to demonstrate vibration sensing for Condition-based Monitoring (CbM). By tracking the vibration analysis data over time, a fault or failure can be predicted, along with the source of the fault. Vibration sensing in an industrial environment adds additional challenges because of the need for robust and reliable sensing methods. Knowing the condition of a machine helps increase efficiency and productivity and creates a safer working environment.

Most solutions that interface with piezoelectric sensors are AC-coupled, lacking DC and sub-hertz measurement capabilities. The Analog Devices Inc. EVAL-CN0540-ARDZ is a DC-coupled solution in which DC and sub-hertz precision are achieved.

By looking at the complete data set from an IEPE vibration sensor in the frequency domain (DC to 50kHz), the type and source of a machine fault can be better predicted using the position, amplitude, and the number of harmonics found in the fast Fourier transform (FFT) spectrum.

The EVAL-CN0540-ARDZ features an Arduino-compatible form factor and can be interfaced and powered directly from most Arduino-compatible development boards.

The EVAL-CN0540-ARDZ incorporates a precision AD7768-1 24-bit, 1024kSPS Σ-Δ Analog-to-Digital Converter (ADC), and an LTC2606 16-bit Voltage Output Digital-to-Analog Converter (DAC). Used as the ADC driver is an ADA4945-1 High-Linearity Differential Amplifier and an LT3092 200mA Programmable 2-Terminal Current Source.

This reference design requires the EVAL-CN0540-ARDZ Board to be plugged into the Terasic Technologies DE10-Nano Carrier Board. The Carrier Board is required to power the EVAL-CN0540-ARDZ board, run the embedded Linux image, and capture and display the data.
