The objective of this graduate work is to provide a manual for load cell projects, specifically ones submitted to flexion and traction - typical forms of load application - based on the use of extensometers and calculations developed on literature. In this work, some basic concepts for assimilation of reasoning are presented, such as Hooke's Law and deformation definitions, types of request and strain gauges, as well as relevant characteristics of current strain gauges and for their correct positioning. In addition, the use of Wheatstone Bridges in their different configurations as meters for comparison is explained, as well as the main types of transducers built by strain gauges, and the use of the Arduino microcontroller as a relevant alternative for reading deformations and for data treatment. Finally, the calculations for two types of load transducers are presented: the binocular model and the model with stress concentrator, and it is expected that the complete design of load cells for industrial applications in the flexion and traction modalities is possible for different materials, from these memorials
