Abstract : The principle , mathematical model of measurement , and implementation procedure of superpositional weigh2 ing system designed successfully with computerized measuring technique are discussed. A lest square decision2making method for measured2data processing is presented , where the analysis and comparison of fitted curves are conducted ac2 cording to the results of measured data. The experiment shows that , by using this method of data processing , the system measurement accuracy and stability can be higher.
Key words : weighing transducer ; mathematical model ; data processing
