| Abstract (English): | The article presents the prototype version of an original weight scale in which a non-conventional supplying circuit of strain gauge load cells is applied. The paper discusses construction of an electrical circuit, the way of strain gauge transducer connection and the measuring procedure. As far as the authors know, this novel electrical circuit and its application in a weight scale system have never been mentioned in literature. The specifications for directreading weight scales typically include readability, repeatability, linearity and eccentricity. The values of these parameters were estimated and used for calculation of the weight measurement uncertainty in the tested measuring range of the designed device. [ABSTRACT FROM AUTHOR] |
| Abstract (Croatian): | Rad predstavlja verziju prototipa originalne vage u kojoj je primijenjeno neuobičajeno napajanje ćelija tenziometra. U radu se razmatra konstrukcija električnog strujnog kruga, način povezivanja pretvarača tenziometra i postupak mjerenja. Koliko je autorima poznato, taj novi električni krug i njegova primjena na sustav vage nisu do sada spomenuti u literaturi. Specifikacije za vage s direktnim očitavanjem tipično uključuju čitljivost, ponovljivost, linearnost i ekscentričnost. Procijenjene su vrijednosti tih parametara i primijenjene u proračunu nesigurnosti mjerenja težine u ispitivanom rasponu mjerenja konstruiranog uređaja. [ABSTRACT FROM AUTHOR] |
