Power amplifier for ultrasonic transducer excitation
Design of the power amplifier for ultrasonic transducer excitation is presented. We assumed that the amplifier output impedance will be significantly lower than the transducer input impedance. Therefore we suggest to used the transformer as voltage step-up and impedance matching element. The transformer influence on the ultrasonic transducer bandwidth and the power transfer efficiency are analy...
متن کاملDesign and Fabrication of a Longitudinal-Torsional Ultrasonic Transducer
A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...
متن کاملA MEMS Transducer for Ultrasonic Flaw Detection
Metal structures can fail because of fatigue crack propagation or because of section loss from corrosion. Regular inspection is required to intercept such failures, and in situ sensors would be a superior technology for that purpose. We have designed and fabricated arrays of MEMS capacitive diaphragm transducers and we report on their performance as pulse-echo detectors in direct contact with s...

متن کاملImproved Ultrasonic Piezoceramic Sandwich Transducer
This paper presents an improved ultrasonic piezoceramic sandwich transducer, utilised for ultrasonic field in narrow lift stations, wet well, flumes and filter beds. The piezoceramic sandwich transducer powered by a signal generator and it is suitable to generate ultrasound with two piezoceramics and the exponential horn at 35 kHz resonance frequency. From the experiments it can be proved that ...
