PZT4 Material 130*121*45 Ultrasound transducer tube Piezo Ceramic
Piezoelectric ceramic tube products are mainly used to transmit and receive radial signals, and two polarization methods, radial polarization and tangential polarization, are often used: radially polarized piezoelectric ceramic tubes are full polarization, high polarization, high polarization. sensitivity. High, when working in its radial vibration mode (low frequency), its electromechanical coupling coefficient is K31, and the conversion efficiency is extremely low, but when working in its thickness vibration mode (high frequency), its performance is excellent; tangentially polarized piezoelectric ceramic tube It is difficult to completely polarize, and the polarization strength is poor, but at the radial vibration frequency (low frequency), its electromechanical coupling coefficient is K33, the conversion efficiency is high, so the sensitivity is high, and due to the higher sound speed V3, under the same diameter conditions lower resonance frequencies can be obtained. Sometimes the piezoelectric ceramic tube is also in the form of axial polarization, but the height of the tube is generally not very large at this time.
Piezoelectric ceramic tubular products are generally used in the field of underwater acoustics or liquid conductive media to transmit axial non-directional ultrasonic signals or receive radial signals, such as: marine towed sonar, floating cables, underwater telephones, Noise jammers, sonar buoys, hydrophones, passive sonar arrays, mine torpedoes, oil well detectors, oil well dredging and sand removal, pipeline ultrasonic descaling and other fields, such as adding conical reflectors to convert radial signals For the axial signal, it not only improves the coupling impedance, but also greatly improves the sensitivity, so it can also be used in the field of gas medium; piezoelectric ceramic tubular products can also use its inverse piezoelectric effect to change its axial length for laser frequency compensation.
