Behavior of materials under stress is evaluated by Acoustic Emission (AE) technique. This NDT technique is used in many applications such as inspection of huge storage tanks, monitoring of welding & shaft straightening process, integrity testing of pressure vessels, study of deformation & fracture in material testing, failure studies of rocks & concretes and many more. This PCI bus based analyzer is four channel data acquisition and analysis board (AEDAQ) using state-of-the-art technology like FPGA & DSP with 14 bit 10 MSPS ADC along with flexible & easy to use Windows 98/2000 based software having advanced GUI. The know-how of AEDAQ with associated software offered which is used to build an advanced NDT system incorporating appropriate piezo electric sensors and low noise pre-amplifiers as per applications. Sensors and pre-amplifiers are bought out items and are available in the market. The system is expandable in steps of four channels.

Advanced PC based Acoustic Emission Analyser for Non-Destructive Testing & Evaluation is an advanced AE System with very powerful state of the art high-speed hardware along with flexible and easy to use 32 bit software tools with Windows 98/2000 based GUI. It is based on PCI bus for high throughput, without loss of AE data, easy expandability with increasing number of channels and efficient performance




Acoustic Emission Data Acquisition Card (AEDAQ) is a full-length PCI card capable of acquiring AE parameters and waveforms from four independent channels. It uses 32-bit Digital Signal Processor (DSP) for waveform processing & control and FPGAs for Real Time AE parameter extraction. Its input section consists of programmable gain amplifiers and band pass filters

32- bit Windows based AEA software allows real time "simultaneous" AE features and waveform processing, display, fast storage and replay. It also enables the user to select and view in real time, multiple 1-D or 2-D feature and waveform activity graphs. It has 1, 2 and 3 dimensional location modes. It supports waveform analysis in frequency and time domains.

INTRODUCTION

Acoustic Emission (AE) testing is a powerful method for examining the behavior of materials under stress. Materials 'talk' when they are in trouble and with the Acoustic Emission Analyser you can listen to the sounds of crack growth, phase transformations, leakage, friction, yielding, debonding, corrosion, wear, capacitive discharge, cavitations, impact etc.

Advanced PC based Acoustic Emission Analyser possesses the ability to detect all AE sources with high sensitivity state of the art hardware and software. It is mainly used to measure and analyse discrete AE signals that cross a pre-defined fixed threshold as well as to monitor & analyse continuously AE signals produced by leaks and wear. It converts each wave packet received by each channel into a set of AE parameters describing the signal. It also has linear and planar AE source location facility.


The Analyser is a PC based Data Acquisition and Analysis Unit, which uses state of the art high speed hardware (Four Channel AEDAQ Card), that includes: fast and accurate Analog to Digital Converters (ADC-14 bit 10 MSPS), FPGA, Digital Signal Processing Chip (DSP). It has completely flexible and easy-to-use 32-bit software tools with Windows 98/2000 based GUI for: system control, parameter management, data acquisition & recording, data analysis, source location, filtering, presentation & documentation of measured data.
