Özet:

In this paper, an electromechanical in-situ measurement method is to be developed for determination of some properties of fuel-oils. Electromechanical impedance spectroscopy (EMIS) method is to be utilized in the measurement technique which will be developed. This method uses piezoelectric sensors that work in electromechanical principles as resonator and dynamically determines the characteristics of a medium that the resonator interacts. EMIS method has been mostly used to determine the dynamic changes in elastic properties of solid materials.This method utilizes the shear horizontal piezoelectric wafer active sensor (SH-PWAS) to generate shear horizontal mode standing waves. Piezoelectric wafer active sensors (PWAS), that are to be utilized in this study, have recently been developed as easily manufactured, small in size and weight, and broad banded transducers to utilize in qualitative and quantitative measurement systems.
