| 摘 要： | 设计了不同材料、不同尺寸承载板式谷物质量流量传感器承载板和不同量程的承载板式谷物质量流量传感器弹性元件,在谷物质量流量模拟加载试验装置上进行了试验，试验结果表明测量精度与承载板和弹性元件的参数密切相关。在此试验基础上,研究了谷物流量对测量精度的影响。试验结果表明，谷物流量在0~2kg/s内谷物质量流量测量相对误差不大于2%,精度较高。当谷物流量超过2.5kg/s时,谷物质量流量测量相对误差超过5%。

| Abstract: | Different materials, different sizes of load plate grain mass flow sensor and different ranges of grain mass flow sensor elastic component were designed. Experiments were finished in the grain mass flow load simulation test device. The experiment results showed that parameters were closely related with precision. On the basis of this test, the grain flow effect on the measurement accuracy was researched. The experiment results showed the error of this load plate grain mass flow sensor was within 2% during the grain flow rate was 0~2kg/s. When the grain flow rate was more than 2.5kg/s, the error exceeded 5%. |
