The application of the piezo quartz resonators (PQR) in liquid media has found a strong dependence of changes in their frequency of oscillation from liquid media permittivity. The present work shows theoretical calculation and experimental research of influence of resonator’s geometrical parameters and permittivity of liquid media on frequency shift of PQR. The effect of sensor’s capacity with different geometrical parameters of capacitor and various permittivity coefficients of liquid media was experimentally determined.
