The Difference between Domestic Electronic Balance Core Technology and International Advanced Technology

China's  electronic balance industry, the production of electronic balance  products in the world, whether it is functional or weighing range and  weighing accuracy of basic low-end products, the majority of technology  and production level is still in the last century between the eighties  and nineties. Circuit  form is mainly constant current source loading, pulse width measurement  method, only a few manufacturers part of the product using other  methods. The number of components used in the circuit multi-line complex, backward function. Foreign  electronic balance circuit from the past complex multi-element  multi-unit electronic circuit to the current advanced  microprocessor-controlled large-scale integrated circuit circuit,  digital circuit technology and software progress to enhance the  electronic balance of the function and accuracy , Weighing stability time is also reduced to about 2 seconds.

Foreign  electronic balance weighing sensor from the beginning of the  electromagnetic force directly to the single-stage lever to the  multi-level lever structure, the development of the current integration  of the module structure, weighing accuracy to achieve a trace or even  super-weighing level. While  the domestic production of electronic balance internal sensor structure  is complex, parts and more connections, assembly complex, resulting in  low efficiency and low failure rate, although the conventional  electronic balance measurement performance with foreign electronic  balance is quite close, but Changshu balance instrument in the design, Manufacturing technology also needs to be improved.
