• Piezoelectric Ceramics Ring For Ultrasonic Cleaning Transducer Pzt4 38*13*6 The precept of the piezoelectric ceramic transducer is that when stress or stress is utilized to the ceramic chip, costs of contrary polarity are generated at the two ends of the ceramic chip, and a current is generated through the circuit This impact is known as the piezoelectric impact Therefore, in the design of ultrasonic transducers, different factors should be considered, resembling acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and how to design and coordinate those points to attain electro-acoustic conversion ideally suited cost As one of those calories transmission network, piezoelectric ceramic transducer has the issue of calories conversion efficiency The conversion efficiency is said to the choice of the transducer material, the form of vibration, the structure of the mechanical vibration method (including the support mechanism), and the operating frequency Therefore, the difficulty of the ultrasonic transmitter is solved There are two materials for piezoelectric ceramic transducers: magnetostrictive metal and piezoelectric ceramics Piezoelectric ceramic transducer is an digital ceramic materials with piezoelectric characteristics The main distinction from a typical piezoelectric quartz crystal that does not contain ferroelectric substances is that the most important ingredient of the crystal part is all ferroelectric crystal grains Ceramics are polycrystalline aggregates with randomly orientated grains, so the spontaneous polarization vector of each ferroelectric grain is also disoriented If a transducer made of such piezoelectric ceramics is put into water, then beneath the action of sound waves, prices could be caused at either ends of the transducer, which is a legitimate wave receiver In addition, the piezoelectric effect is reversible If an alternating electrical area is applied to a piezoelectric ceramic sheet, the ceramic sheet will develop into thinner and thicker from time to time, and it's going to vibrate and emit sound waves In order to make the ceramic reveal macroscopic piezoelectric properties, the piezoelectric ceramic must be polarized in a strong DC electrical area after firing, and the top face is subjected to multiple electrodes, in order that the polarization vector of the unique disordered orientation is preferentially oriented within the direction of the electric field, and after the electrical area is removed , The piezoelectric ceramic after polarization medicine will maintain a certain macroscopic residual polarization strength, in order that the ceramic has a certain pressure Piezoelectric ceramic discs, ceramic rings, rectangular piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of assorted specs would be customized Product Description: Ultrasonic stress ceramic wafer product features: 1 The impedance is lower than 2 ohms 2 The waveform is steady three High electromechanical conversion efficiency four Low dielectric loss 5 Low calorific price The piezoelectric ceramic ultrasonic transducer is acceptable for ultrasonic welding kit and ultrasonic cleansing equipment It is especially made from high-power transmitting piezoelectric ceramics The ultrasonic transducer is a tool that may convert high-frequency electrical energy into mechanical energy As an calories conversion device, its operate is to convert the input electric power into mechanical power (ultrasound) and then transmit it out, and it consumes a small a part of the ability by itself specification Dimension(mm) Radial frequency(KHz) Capacitance(pf) Dielectric dissipation factortanδ(%) Electromechanical coupling coefficient(Kr) ImpedanceZr(Ω) Thickness frequency(KHz)) Mechanical high quality component (Qm) PLS-YHJP-25103 Φ25×Φ10×3 66 1240±12% ≤0 ≥0 ≤15 683±5% 800 PLS-YHJP-25104 Φ25×Φ10×4 66 930±12% ≤0 ≥0 ≤15 512±5% 800 PLS-YHJP-40125 Φ40×Φ12×5 forty five 2070±12% ≤0 ≥0 ≤15 410±5% 800 PLS-YHJP-40155 Φ40×Φ15×5 forty two 1960±12% ≤0 ≥0 ≤15 323±5% 500 PLS-YHJP-40176 Φ40×Φ17×6 40 1555±12% ≤0 ≥0 ≤15 341±5% 800 PLS-YHJP-40205 Φ40×Φ20×5 37 1700±12% ≤0 ≥0 ≤15 410±5% 800 PLS-YHJP-50206 Φ50×Φ20×6 33 2490±12% ≤0 ≥0 ≤15 341±5% 500 PLS-YHJP-501765 Φ50×Φ17×6 34 2430±12% ≤0 ≥0 ≤15 315±5% 800 PLS-YHJP-50236 Φ50×Φ23×6 31 2340±12% ≤0 ≥0 ≤15 341±5% 800 PLS-YHJP-50276 Φ50×Φ27×6 29 2100±12% ≤0 ≥0 ≤15 341±5% 800 PLS-YHJP-603010 Φ60×Φ30×10 25 1922±12% ≤0 ≥0 ≤18 205±5% 800 FOR MORE OEM SIZE WELCOME TO ENQUIRE SALERS
