An FPGA-based high-performance wireless vibration analyzer

In this article, an Field Programmable Gate Array (FPGA) based high-performance wireless vibration analyzer that performs high sample rate tri-axes (horizontal, vertical, and axial) vibration monitoring and analysis, is presented. The custom designed compact size wireless analyzer can be mounted on difficult to access as well as rotating parts of the machinery so as to perform vibration based condition monitoring. Based on the measured performance and power consumption, the analyzer not only achieves the performance goals for high-sample rate (i.e. at 50 kHz) tri-axes vibration data processing but, also achieves operational lifetime of more than three years for duty-cycle durations of more than 4 hours.
