Caracterização das fontes e expressão da incerteza de medição em processos de medições lineares do laboratório: UTFPR-LAMEC

Abstract

In many areas of metrology, the estimation of uncertainties of measurement shown extremely important to define the real measurement result. Moreover, it shows a remarkable difference in measurements due of its quality, credibility and adding value to laboratories in manufactured products. Despite its importance, the measurement uncertainty has not yet been fully disseminated, especially in academic circles. The idea of this paper is to apply in the Mechanical Metrology Laboratory of UTFPR, all concepts related to uncertainty of measurement in linear measure processes, from simple tools such as calipers and micrometers, to more and ultrasound measurement devices. There was also the assessment of Uncertainty Sidekick software as calculation of uncertainty, and the creation of Excel spreadsheets based on the theory in order to not only calculate the uncertainty in the measurements as well be used in future measurements.
