| description | Nowadays automation has an important place in metrology, because allows to improve the quality of the measurement results.
This paper presents the design, construction and automation of a system for calibration of weights between 100 g and 500 g, which consists of an artificial vision system employed to determinate the standard and test masses. A rail system guided by a control loop performs weighting and comparison cycles; the data obtained is exported to a spreadsheet program in such way that at the end of the process it is possible to directly print the calibration certificate for each weight.
The system reduces some errors generated by handling of the operators, such as eccentricity (incorrect weight placement), repeatability (force used to place the weights on the scale) and heat transfer from operator to weights.
The system construction has been made inside of a climatic chamber, thereby the problems caused by temperature and humidity changes will be reduce significantly, decreasing the uncertainty by air buoyancy.
This system offers an alternative to calibration systems used today, which improves weight calibration (measurement, accuracy and precision), decrease operative time, acquisition and maintenance costs because it reduces the space to be controlled and automates most of the manual process |

En este artículo se presenta el diseño, construcción y automatización de un sistema de calibración de pesas entre 100g y 500g, constituido por un sistema de visión artificial para determinar la masa prueba y la masa patrón. Un sistema de rieles guiados por un lazo de control realizan el ciclo de pesaje y comparación; los datos obtenidos se exportan a una hoja de cálculo para imprimir el certificado de calibración al terminar el proceso. Todo el proceso sigue la normativa técnica colombiana 1848:2007. Este sistema elimina algunos errores generados por la manipulación humana, entre estos: excentricidad (ubicación incorrecta de masas), repetibilidad (fuerza con que se ubica la pesa sobre el platillo), y transferencia de calor del operario hacia las masas. La construcción del sistema se realiza al interior de una cabina de ambiente controlado, por lo tanto los problemas generados por los cambios de temperatura y humedad relativa serán reducidos significativamente, disminuyendo la incertidumbre por empuje de aire. Con este proyecto se ofrece una alternativa a los sistemas de calibración existentes actualmente, que mejora calidad en la calibración (exactitud y precisión en la medición), disminuye tiempos de operación y reduce costos de adquisición, adecuación y mantenimiento, ya que se reduce el espacio controlado y se automatiza gran parte del proceso manual. 2013-10-28 2024-10-10T02:25:04Z 2024-10-10T02:25:04Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://purl.org/coar/resource_type/c_6501 http://purl.org/coar/version/c_970fb48d4fbd8a85 https://revistas.uan.edu.co/index.php/ingeuan/article/view/363 https://repositorio.uan.edu.co/handle/123456789/10439 spa https://revistas.uan.edu.co/index.php/ingeuan/article/view/363/303 https://creativecommons.org/licenses/by-nc-sa/4.0 http://purl.org/coar/access_right/c_abf2 application/pdf UNIVERSIDAD ANTONIO NARIÑO INGE@UAN - TENDENCIAS EN LA INGENIERÍA; Vol. 4 Núm. 7 (2013) 2346-1446 2145-0935 |
