Desenvolvimento de programa para verificação de paquímetros do Laboratório de Metrologia da UACSA

Abstract

The reliability of measurements in measurement instruments is crucial for or-ganizational per- for-mance. Although this topic is addressed in several national and international mentions, it lacks gui-dance for performing instrument checks asser-tively. This study aims to contribute in a significant way to increase the quality of the measurements performed in calipers, developing a program, in Python language, which performs the necessary calculations for verification and at the end generates a verification report. Ensuring an internal quality control of these measuring instruments belonging to the metrology laboratory of the Academic Unit of UFRPE-UACSA. A case study was developed in which the calculations, corresponding to the sources of uncer- tainty, performed manually were compared with those obtained by the software. In addition, an error curve was generated, allowing a visual analysis of the instrument's behavior in operation between verifications and determining a temporal correction factor. The application of the pro- gram proved to be effective, facilitating the construction of verification reports, with a drastic reduction in time, compared to that spent to prepare a manual report. It also allowed the valida- tion of its operation. This work may contribute to applications in academic and professional environments, allowing a simple way to verify and mea-sure the measurement uncertainty of calipers.
