Abstract

Supported by FAPESP, Sensis developed the basis of the DM42 product, an acoustic emission monitor which is on the market today. Currently, other competitor companies are manufacturing monitoring systems which enable multisensor functions and advanced signal treatment options. The question is that DM42 can only cope with acoustic emission signals, because the hardware adopted is cheaper and more limited regarding signal treatment options. With this project, the company proposes the first high frequency acoustic emission monitoring system to use digital processing of signals (DPS). In its first phase, the objective of the project was to verify the technical viability of using modern and inexpensive versions of DPS systems for application in monitoring processes. The new system needed to be flexible enough to have its filtering parameters defined by software, or even the execution of Fourier transformations for the analysis of processes in a low cost piece of equipment. This first phase of the project was approved and concluded successfully, and the proposal for phase 2 is to carry out research on the definition for a prototype of the entire system. This new prototype should be tested in production environments to examine the new functionalities that could be applied. (AU)
