Izdelava in umeritev precizijske tehtnice

Kahteran, Alen (author), Širca, Simon (mentor)

V zaključnem delu sem sestavil precizijsko tehtnico z natančnostjo pod 100 mg. Predstavljene so različne merilne celice, njihove fizikalne lastnosti ter njihove uporabe v različnih industrijah. Za izdelavo tehtnice sem uporabil merilno celico z uporovnimi lističi, ovrednotil tako njene lastnosti kot lastnosti ostalih delov v tehtnici. Opisal sem uporabljene algoritme za zmanjšanje šuma ter pretvorbo bitnega števila v gramski zapis.

Abstract

The thesis presents the assembly of a precision weighing scale with an accuracy of better than 100 mg. It presents different load cells, their physical properties and their use in various industries. It evaluates the features of the strain gauge load cell and the features of other components of the scale. It also contains a description of algorithms used for the reduction of noise and conversion from bits to grams.
