Abstract

The project aims to develop a deformation gauge for application both in test laboratories and the research of new materials and in the civil engineering structures. The desired equipment will have a very precise measurement system (better than 0.1 per cent) and high resolution (1 micrometer/meter), the functions of which will be monitored and controlled by a microcomputer control system. Furthermore, a communication interface will be made available compatible with standard IBM/PC microcomputers, so as to facilitate the analysis of the data through specific software programs. Since it possesses predominantly digital properties, the intention is to implement several of its circuits by means of matrixes of logic circuits (FPGA), which are more efficient, consume less power and occupy less space. The conclusion of this project will deliver into the national market a quality product of flexible use, and high technological value, since at the moment no other such manufacturer exists in this market. The equipment has guaranteed applications in the areas of materials testing and the monitoring of civil engineering works. (AU)
