WAVEGUIDE PIEZOELECTRIC PULSE PRESSURE TRANSDUCER

This paper presents a waveguide piezoelectric pressure transducer based on piezoceramics (TsTS-19), the reactive acoustic waveguide of which is made of a mixture of materials related to non-Newtonian fluids.Its design is described, a calibration technique is proposed, and experiments are conducted to determine the value of the conversion factor.Calibration units are presented, the operating principle of which is based on the method of a falling weight and pulsed electromechanical action.
