Design of instrument for measuring the electrical conductivity of ice cores

For the application of electrical conductivity measurement of ice core in the analysis of ice core processing, foreign hand-held electrical conductivity measurement unit is developed and updated by using servo motor to automatically control electrical conductivity measurement. while the corresponding human-computer interaction platform is designed to display and save the measured data and control the speed and direction of the motor. The system takes STM32F103 processor as the core and combines with ADS1240, grating scale, servo motor, high-voltage module and temperature sensor, realized the functions of data collection, data transmission and data storage. The test shows that the system can accomplish the electrical conductivity measurement of ice core stably. And compared with abroad, it has a higher precision and wider measurement range, which meet the requirements of the design.
