Study on insulation technology of the electrode conductivity sensor has important application value in engineering. It is used in measuring the conductivity of water, which is widely applied in the industry, aerospace and marine areas of research and development and other fields. This paper introduces the working principle of the electrode conductivity sensor, and studies on its insulation characteristics. The capacitor in series circuit is designed. The experimental results show that this scheme can effectively improve the insulation resistance of the sensor, which is increased by two orders of magnitude. And it provides a strong guarantee for the long-term stability and service life of sensor.
