| Abstract: | In this paper,based on the different capacitance characteristic between air,ice and water,a new capacitance sensor model of ice thickness which is used for testing ice thickness has been designed.PS021 a Capacitance-to-Digital chip,which is developed by acam,could convert sensor signal into digital signal is used in this detecting system.The result of experimental data analysis shows that this New sensor has the characteristics of simple structure,high reliability and can be used for continuous automatic monitoring ice thickness and water level under ice in winter. |
