Measurement Of Mechanical Vibrations Or Ultrasonic Waves
(AREA)
Abstract
The proposed ultrasonic piezoelectric transducer of mechanical parameters contains a piezoelement designed as a step ultrasonic concentrator with electrodes that are arranged at the end and step surfaces of the concentrator, an oscillator, a measuring unit, a membrane, and an inertial mass. The inertial mass is arranged so that mechanical contact with the upper part of the concentrator is provided.
