Investigation of Water Electrical Parameters as a Function of Measurement Frequency and Concentration Using Cylindrical Capacitive Sensors, M.Sc. Thesis Sharif University of Technology ; Golnabi, Hossein (Supervisor) ; Gobal, Fereydoon (Co-Advisor)
Abstract
The electrical conductivity of the solution has been one of the important physical quantities in many application. In this respect many probes and devices such as conductive sensors have been devised. In this study electrical properties of different water samples at frequency step range of 100-100000 Hz are measured by using the long cylindrical capacitive sensor and a measuring module (LCR-703). Operation of the capacitance measurement module for such probes is based on the auto balancing bridge method. Comparison of the measured capacitances and measured resistances for different water samples shows a decrease by increasing the measurement frequency. In another study the dielectric...
