Abstract: An accurate training on measurement techniques and measurement system design can be obtained by carrying out real experiments with real electronic components and circuits. The measurement system presented in this paper performs the computer aided study of the bending stress sensor. This experimental system is very useful for engineering undergraduates because they can test the theoretical knowledge about measurement techniques, sensors and transducers, signal conditioning circuits, data acquisition boards, signal processing methods and computers (hardware and software). The bending stress sensor consists of four strain gauges connected in a full-bridge circuit, and it transforms the load or force into measurable voltage change. An instrumentation amplifier and a noise suppression circuit and amplifier are designed for conditioning the output voltage of the bending stress sensor. The computer aided study of this sensor imposes a data acquisition board with a microco!
ntroller, adequate software and a friendly user interface. The procedure for strain gauge sensor study supposes the following four stages: assignation of the measurement points, plotting the transfer characteristic of the force transducer, computing some parameters of the force transducer (zero error, differential sensitivity, relative sensitivity), weighing some objects using the strain gauge sensors. The architecture and design considerations for signal conditioning module and data acquisition board are also presented in this paper.
