Add to ORKGThe work deals with methods of measuring the parameters of the ultrasonic beam generated by piezoelectric sensors. The theoretical part contains a literature search of methods for the analysis of the ultrasonic beam generated by piezoelectric transducers with dimensions of units of millimeters. The problematics of measurement using piezoelectric or optical fiber hydrophones is investigated in more detail. The scope of the practical part of the work is the design and implementation of measuring equipment that allows spatial analysis of the beam during propagation by a complicated signal path, for automotive level and concentration sensors of the company Vitesco Technologies s.r.o. The system uses a hydrophone method to measure the ultrasonic...
