Comparison of microstrain indicators measurements based on Anderson´s Loop and Wheatstone Bridge

This paper describes two types of microstrain indicators systems saved on two technologies: Wheatstone bridge and Anderson current loop. These systems have been developed using low cost components and low power consumption.. An analytical study was made and compared with the measurements of the indicators system. The main goal of this research is implement a small wireless---indicator to be used in a wireless sensor network. This paper presents a comparison and evolution of strain measurement methods.
