| Abstract: | A kiad of electro-magnetic force compensation balance using pulse-width modulation is the modern high accuracy electronic balances (analytical and micro-analytical).The main features of such balance are the simple circuit, high resolution and lower cost. This paper discusses in detail its principle of measurement, A/D converter and several important factors which are the basis for the design. The paper also outlines the system of microprocessor. |
