Detailed analysis of the principle of sorting scale

The principle of the sorting scale, the sorting scale adopts the continuous dynamic automatic weighing method to check the net weight of the object, and is equipped with an alarm or automatically removes the tissue, so as to achieve the net weight inspection on the production line without shutting down. It is suitable for checking the shortage of materials in packaging bags and packaging cartons. When the raw material is transferred to the middle of the scale, the working pressure is applied to the weight sensor, the sensor deforms, and the characteristic impedance is changed. In addition, the application encourages the working voltage to change and outputs a changed pulse signal. The signal is amplified by the operational amplifier and output to the MIXIR special analog-to-digital converter, which is converted into a convenient analog signal and output to the MIXNR special microcontroller for calculation and manipulation. According to the key command and its optimization algorithm, the results are exported to the display screen, and the net weight data information of the information object is displayed. Weighing objects in activities, its dynamic weighing equipment composed of weight sensors and other parts is not a closed-loop control fully automatic automatic control system, but a special-purpose data collection system software. That is, according to the characteristics and values u200bu200bof the data signal obtained by the dynamic weighing equipment of Meixinrui, the direct current component that is proportional to the quality is separated from it. Therefore, the current dynamic weighing method can also be said to be based on signal analysis. A way of leading. The key to the accuracy caused when the measured value replaces the specific value lies in the impact of dynamic weighing and the dynamic characteristics of the weighing system software itself (that is, the transfer function of the weighing device).
