COMPANY INTRODUCTION

The IDK’s AET system is composed of sensors, pre-amplifiers, DAQ boards and an analysis computer. Sensors to extract elastic waves signal, pre-amplifiers to amplify the signal output from the sensors, IDAQ-8 board (IDAQ: IDK’s Data Acquisition Board) to convert analog signals to digital values, and analysis of the waves with Fast Fourrier Transform(FFT) based on FPGA application perform excellent resolution and reliability with low cost. The acquired analysis results
