| Abstract: | A new non-contact measurement sensor is developed for surface water conductivity measurement based on the capacitively coupled contactless conductivity measurement technology,and a non-contact conductivity measurement system is constructed in this paper.In order to optimize the parameters of the sensor structure and analyze the effect of impurities on the system,a simulation model of the sensor is established using finite element method.Test results show that the measurement system is feasible and suitable for surface water conductivity measurement;the system features simple structure,non-contact electrodes and strong anti-impurity-interference capability,and can satisfy the requirements of long-term and real-time on-line field measurement of surface water conductivity. |
