Abstract

Tema ovog rada je mjerenje sile. Za mjerenje sile korišten je tenzometarski most, koji kao rezultat daje promjenu napona proporcionalnu s promjenom sile. Za ispravan rad sklopova u uređaju potrebno je imati vrlo stabilno napajanje i za to je bilo potrebno izvesti bipolarno napajanje. Kako je dobiveni signal male amplitude, bilo ga je potrebno pojačati i za to je korišteno instrumentacijsko pojačalo. Uslijed nesavršenosti komponenti, javlja se napon pomaka koji je potrebno kompenzirati. Dobiveni signal poslan je na analogno – digitalni pretvornik i poslan dalje na analizu i obradu u mikrokontroler.

Abstract (english)

Subject of this paper is force measurement. For that purpose load-cell was used which, on it's output, generates voltage proportional to force apllied on it. In order to avoid malfunctions, stabile power supply is neccessary and for that purpose it was dual power supply. Signal generated by load-cell is low-amplitude, so instrumentation amplifier was used. As a result of component imperfections, offset voltage occured and it needed to be compensated. Analog signal from the amplifier was converted to digital in analog – digital converter and it was sent for further analysis and processing to microcontroller.
