Przyrządy witrualne wspomagające nauczanie podstaw metrologii

W artykule przedstawiono wybrane aplikacje opracowane w środowisku LabVIEW. Dotyczą one podstaw metrologii m.in. opracowania pojedynczego wyniku oraz serii wyników pomiaru. Przedstawiono przyrządy wirtualne, które symulują podstawowe układy stosowane w metrologii. Ich zastosowanie wzbogaca i uatrakcyjnia proces nauczania.

In this article the various applications elaborated in LABVIEW environment were presented. These applications show the selected measurement problems occurring in teaching of metrology principles in the Department of Metrology and Diagnostic Systems at Rzeszow University of Technology. Two of the mentioned applications are dedicated for simulation of DC voltage measurement. Measurements can be done by analogue or digital virtual voltage meters. The expression of uncertainty is the most important task in metrology as well for single value of measurement as for a series of values. The next application makes possible to assess uncertainty of series of measurement results using the Gaussian distribution or the Student's t-distribution. The another application shows problems accompanied with balanced and unbalanced bridges. The resistive sensor Pt100 sensing the temperature of environments was use as element of unbalanced bridge. The last two applications were developed to explain the ideas of analogue to digital conversion. In this article two virtual ADC converters using successive approximate and dual slope were presented.
