英文摘要：

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.
