At a company that manufactures blood pressure monitors for diagnosing peripheral arterial disease, it was found that the existing method of calibrating pressure sensors was too slow and represented a bottleneck in the production process. As part of the thesis, we defined the technical specifications required by the monitor and created four conceptual designs. This was followed by the selection of the best design, with an emphasis on the functionality and cost of the entire system. Through calculations, we precisely determined the specifications needed for each component. We designed, tested, and analyzed a prototype, manufactured housing, and integrated the components into it. The Modbus RTU protocol, via an RS485 interface, enabled command transmission from a personal computer. We conducted multiple tests and confirmed that the system operates as specified in the requirements. Finally, we integrated the device into the production system, which accelerated the production process.
