Abstract
A composite torsional quartz transducer has been developed for the shear ultrasonic measurements of aqueous solutions in the frequency range from 10 to 100 kHz. In order to prevent the electric interaction and low contact angle between the transducer and water, a torsional quartz crystal transducer is attached to a fused quartz rod whose surface is partly gilded by evaporation. The accuracy of +/-60 dyn/cm2 for the rigidity and +/-0.03 cP for the viscosity is attained by use of this transducer.Keywords
