Abstract
Za kakovostno pripravo mešanic sipkih materialov je potrebno natančno odmerjanje sestavin. Istočasno pa je velikokrat za prevoz takih surovin uporabljena samokolnica. V diplomskem delu smo zasnovali in izdelali samokolnico s tehtnico, ki ima merilno območje od 0 do 100 kg. Samokolnico smo umerili po priporočilih EURAMET-a in določili ponovljivost, nelinearnost, histerezo in ekscentričnost tehtnice. Določili smo tudi dosegljivo razširjeno merilno negotovost, ki je 0,70 % merilnega razpona. S pregledom trga smo ugotovili, da je proizvodnja smiselna le v manjših količinah.

Title:Development and metrological evaluation of a wheelbarrow with a weight scale
Abstract:
For the quality preparation of mixtures containing loose materials, precise dosing of ingredients is necessary. At the same time, a wheelbarrow is often used to transport such raw materials. In this diploma thesis, we designed and manufactured a wheelbarrow with a weight scale, which has a measuring range from 0 to 100 kg. We calibrated the wheelbarrow following the EURAMET guide and determined the repeatability, nonlinearity, hysteresis and eccentricity of the scale. The achievable expanded measurement uncertainty of the wheelbarrow with a weight scale is 0.70% full scale. By reviewing the market, we found that production only makes sense in smaller quantities.

Keywords:weight scale, wheelbarrow, product development, metrological evaluation, market overview
