| Abstract: | A improving scheme of realizing the precision and the stability of the multi-sensor electron balance is presented. Considering the conditions of weighing system, the forces of sensors are analyzed and the system structure is improved to enhance the system stability by the research of the factors which affect the weighting system precision. The causes of nonlinear of the multi-sensor system are discussed. According to the sensor input- output characteristic curve,linear of muhi-sensor is processed by the dynamic compensative circuit. The system is optimized by the means of hardware. System precision and stability is greatly improved. |
