Abstract: A PC based instrument for the measurement of dielectric constant in liquids has been developed. It is based on the technique that utilizes frequency measurement for determination of capacitance using the personal computer as a tool. The change in frequency of XR2206 function generator, when the liquid forms the dielectric medium of the dielectric cell, is measured with a personal computer. The programmable interval timer 8254 available in the DIOT card is used to measure the frequency, which in turn determines the capacitance of the cell and dielectric constant. The necessary software is developed in C language. The instrument system covers a wide range of dielectric constant for various liquids. The system is reasonably successful in measuring dielectric constant with an accuracy of 0.5 %. The paper deals with the hardware and software details.


Keywords: Dielectric constant; XR2206 function generator; Frequency measurement and Computer based system
