Apply the basics of industrial instrumentation, methods for conditioning electrical signals and methodologies for the use of sensors, transducers, converters a / d and d / a, and microcontrollers, the implementation of data acquisition systems. INTRODUCTION
man has always been nature acquiring data for decision making: the ambient temperature, the direction wind, the volume of water from a reservoir, is commonplace. Do not say in the task of transforming the environment, or build better rooms, furniture manufacturing, food production, particularly in industrial work in the areas of chemistry, medicine, industrial process control etc.. .
Currently, the use of computers and microprocessors with sophisticated techniques of digital signal processing has applications in all areas of measurement, instrumentation, process control, and analysis of physical variables. The digital effort is favored for many reasons, among which high immunity noise, ease of data storage, and the relative ease of data transmission. Additionally, there are many algorithms for processing digital data, providing efficient data analysis. Generally a data acquisition system can be composed of the following items.
