Essay

To urgent questions of advancing of known piezoelectric transducers and creation of new piezoelectric transducers of viscosity of a liquid dissertation the activity is dedicated. The mathematical model of a piezoelectric transducer is constructed and is studied. The new ultrasonic method of measurement of viscosity is encompass byes following: the damped oscillations in piezoelectric piezotransformer are excited, number of oscillations, which one exceed a fixed level, measure. The relation of an oscillation damping to a diving depth is established. The diving depth of the vibrator for maintenance of accuracy of measurements is necessary for fixing. It is possible to use ultrasonic concentrators in piezoelectric transducers of viscosity of a liquid for increase of power of vibratory process, dilatings of measurement range of viscosity. The converter can be sectioned into two parts: the vibrator, is adjoined to which one the probe on rigid link. The probe for increase of accuracy of measurements of viscosity moves in a liquid. The contact of the vibrator to a liquid is eliminated, vibrators, which one provide reciprocal motion of the probe are applied. Keywords: a piezoelectric transducer, viscosity, ultrasonic method, concentrator.
