| Resumo: | Pyrometers are instruments that measure surface temperature from the radiation emitted by them. They do not have a Brazilian norm, NBR from ABNT, that describes the proper calibration procedure for such instruments. Therefore, due to the existence of this bottleneck, there is a need to develop a proposed procedure, which in addition to guiding the step-by-step that the operator must follow, also provides an environment for the calculation of uncertainties, and linked to this, the automatic generation of calibration certificates.
To achieve this objective, tests were carried out for data collection with the MT-350 pyrometer from Minipa brand, and the blackbody T-500PIR from Presys brand. In addition, Google Sheets and Google Apps Script were used to develop a spreadsheet aimed at performing uncertainty calculations, besides being the means used to generate the calibration certificate.
From the proposed procedure it is possible to account for different sources of uncertainty involved in the calibration of pyrometers, in addition to providing an automation in the generation of certificates for these instruments. This project was restricted to pyrometers only, but it serves as a basis for the improvement and construction not just for researches with this specific theme, but also aimed at other measuring instruments. |
