| 摘 要： | 提出了一种结构简单的新型非接触电导率传感器。从原理出发,采用ANSYS有限元方法,通过建立有限元模型、定义材料属性、网格划分、设置边界条件、加载和求解等,得到了溶液电导率分别与传感器电感和电容之间的关系。利用该传感器对几种已知电导率溶液进行了测试,结果显示其测量的最大相对误差为0.64%,从而证明所提出的传感器测量方法不仅测量精度可行,还提高了测量的冗余度和可靠性,具有很高的商业应用价值。

| Abstract: | A new type of non-contact conductivity sensor with simple structure is proposed.The relationship between solution conductivity with sensor inductance and capacitance can be obtained based on the theory and finite element method （FEM） by ANSYS,through setting up FEM,defining material property,meshing,establishing border conditions,loading,solving,and so on.Test on several known conductivity solution is carried out using the sensor,the results show that the maximum relative error of the measurement is 0.64 ％,therefore it is proved that the proposed sensor measurement method not only has feasible measurement precision,but also improves measurement redundancy and reliability,and has high commercial application value. |
