This project aims to develop a force sensor, which one should measure the load applied to on the top of the platform. This load is going to be a horizontal force with a limit value of ±3000N.

The study aims to figure out how to develop this project and make it, this project was planned and executed according to circumstances created by COVID-19. The first step is to select the strain gauges that are going to be used and the type of Wheatstone bridge. After the Wheatstone bridge, the signal must be amplified and then registered and presented to the computer.

To reach this a lot of books and articles have been studied. For the realization of this project have been used 3 software. First, Multisim which has been used to simulate the Wheatstone bridge and know what the voltage at the output of the circuit would be. The second is the NX FEM by Siemens, which was used to send the simulation of the platform and thus see results as deformation. Finally, Abaqus has also been used to make a 2D prototype and, like the previous one, to see the deformations in the platform. Due to the COVID-19, the assembly of the device has been impossible to carry out. Despite this, all the theoretical part has been carried out and also guidelines how to fit the strain gauges. It has been tried to do as much as possible and it has been explained as far as possible the steps that should be followed to assemble the device. Therefore, even if the practical part cannot be done, the device should be able to be perfectly assembled simply by following the instructions.
