EVAL-CN0579-ARDZ

Quad-Channel IEPE Vibration Sensor Measurement System.

Overview

Condition-based monitoring (CbM) 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.

The EVAL-CN0579-ARDZ 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 (DC to 50 kHz), 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 (FFT) spectrum.

Features:

• Quad Channel IEPE-Compatible Vibration Sensor Interface

• Channel Independent Excitation Source and Sensor Bias Removal Circuitry

• Analog Overvoltage and Undervoltage Protection

• Sensor Frequency Response from DC up to 54 kHz

• Synchronized, Full Bandwidth Data Measurement and Capture

Applications:

• Machine condition-based monitoring and predictive maintenance

• Industrial vibration sensing and fault detection

• IEPE/ICP piezoelectric and MEMS sensor data acquisition

• DC-coupled wideband vibration analysis (DC to 50 kHz)

Recommendations

People who follow the flow outlined below have a much better experience. If you have any questions, feel free to ask on our EngineerZone, but before that, please make sure you read our documentation thoroughly.

To better understand the EVAL-CN0579-ARDZ, we recommend using it together with a supported FPGA carrier board - either the Terasic DE10-Nano or the Digilent Cora Z7 - running the ADI Kuiper Linux image.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
