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.
