Diseño y fabricación de un baño termostático de líquido para la calibración de termómetros en rangos de baja y alta temperatura

Abstract

In the field of biomedicine, equipment calibration is essential to guarantee the reliability of medical devices. This process involves verifying and regulating their accuracy, ensuring that the values obtained are as close to reality as possible and allowing for correct diagnoses and safe treatments for patients. Currently, Clinical Solutions SAS lacks a means to perform precise thermometer calibration, especially when temperatures below 0 °C or high and stable temperatures are required. Therefore, the purpose of this project is to provide the company with a simple and intuitive way to perform precise calibration of thermometers at both low and high temperatures using standard temperature measurement equipment. This project focuses on designing, programming, and implementing a low- and high-temperature thermostatic bath for thermometer calibration. To achieve the desired temperature ranges, a compression system and a heating device are used, all managed by a microcontroller. The microcontroller also allows for wired connection, monitoring, and control of the thermostatic bath. The project is expected to offer high precision and meet the minimum standards for thermometer calibration, maintaining stability at the user-requested temperature while providing useful and reliable data for calibration purposes.
