Due to greater productivity in the auto industry and the high competition in the current market, employees are required to perform repeated movements and often, with short intervals of rest. This daily exposure causes muscle tension and overloads occasional, thus creating problems and psychosocial stress. Currently companies are concerned with the welfare of the employee, where the main focus is product quality and life of the worker, thus justifying such a study. Therefore , this technical work to assist the master's thesis of graduate student Daniel Rodriguez , was developed with the objective is to analyze , develop, design and construct a coupled to a load cell device simulating a stitcher to be used in an industry the posts stapling upholstery of seats . Are the stages of design and construction detailed in this work and its positive results in relation to the technical part of the study

In engineering projects, it’s fundamental to determine the active loads in components in order to guarantee acceptable values of safety and reliability according to project specifications. On the other hand, force measurement methods might be very complex and impracticable in some cases and, so that, load cells with eletric resistance strain gages can be applied as a simple and accurate option to measure the required load. The main purpose of this paper is to present the development of a load cell that measures uniaxial forces using electric resistance strain gages without being influenced by the location of the loading in a cantilever beam. For that, it was taken as basis a secondary purpose which is to present a general study of basic and wide concepts about transducers, load cells and extensometers primarily. Information such as: loading and measurements types, characteristics of the presented devices as well as factors that influence its functioning, the most common kinds of Wheatstone bridge links, the main points of a load cell project, cements used to fix extensometers and, finally, the project itself with the tests of the built transducer are presented. By the end of this paper, all the results are shown and analyzed, concluding about the designed load cell and the work itself
