• Round Shape Piezo Ceramic Components 40x20x5mm For Ultrasonic Transducer Piezoelectric Element AssembleThe principle of the piezoelectric ceramic transducer is that when stress or stress is utilized to the ceramic chip, fees of opposite polarity are generated at the two ends of the ceramic chip, and a contemporary is generated during the circuit. This impact is called the piezoelectric effect. Therefore, within the design of ultrasonic transducers, various factors ought to be considered, akin to acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and learn how to design and coordinate those factors to attain electro-acoustic conversion. ideally suited value. As a kind of energy transmission network, piezoelectric ceramic transducer has the difficulty of energy conversion efficiency conversion efficiency is expounded to the selection of the transducer material, the shape of vibration, the structure of the mechanical vibration components (including the help 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 electronic ceramic materials with piezoelectric characteristics. The main contrast from a standard piezoelectric quartz crystal that could not contain ferroelectric elements is that the key detail 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 also is disoriented a transducer made of such piezoelectric ceramics is put into water, then beneath the action of sound waves, charges can be brought about at both ends of the transducer, which is a legitimate wave receiver. In addition, the piezoelectric impact is reversible. If an alternating electric discipline is utilized to a piezoelectric ceramic sheet, the ceramic sheet will develop to be thinner and thicker from time to time, and it'll vibrate and emit sound waves. In order to make the ceramic show macroscopic piezoelectric properties, the piezoelectric ceramic must be polarized in a powerful DC electrical field after firing, and the top face is subjected to a number of electrodes, in order that the polarization vector of the original disordered orientation is preferentially orientated within the course of the electric field, and after the electrical field is eliminated , The piezoelectric ceramic after polarization treatment will hold a certain macroscopic residual polarization strength, simply so the ceramic has a definite pressure. Piezoelectric ceramic discs, ceramic rings, oblong piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of assorted specifications could be personalized Description:Ultrasonic pressure ceramic wafer product features:1.

Low calorific price The piezoelectric ceramic ultrasonic transducer is acceptable for ultrasonic welding kit and ultrasonic cleansing equipment. It is mainly manufactured from high-power transmitting piezoelectric ceramics. The ultrasonic transducer is a device that may convert high-frequency electricity into mechanical energy. As an calories conversion device, its function is to convert the input electrical energy into mechanical energy (ultrasound) after which transmit it out, and it consumes a small a part of the power through itself. specificationDimension(mm)Radial frequency(KHz)Capacitance(pf)Dielectric dissipation factortanδ(%)Electromechanical coupling coefficient(Kr)ImpedanceZr(Ω)Thickness frequency(KHz))Mechanical quality aspect (Qm)PLS-YHJP-25103Φ25×Φ10×366±12%≤0≥0≤15683±5%800PLS-YHJP-25104Φ25×Φ10×466±12%≤0≥0≤15512±5%800PLS-YHJP-40125Φ40×Φ12×545±12%≤0≥0≤15410±5%800PLS-YHJP-40155Φ40×Φ15×542±12%≤0≥0≤15323±5%500PLS-YHJP-40176Φ40×Φ17×640±12%≤0≥0≤15341±5%800PLS-YHJP-40205Φ40×Φ20×537±12%≤0≥0≤15410±5%800PLS-YHJP-50206Φ50×Φ20×633±12%≤0≥0≤15341±5%500PLS-YHJP-501765Φ50×Φ17×6±12%≤0≥0≤15315±5%800PLS-YHJP-50236Φ50×Φ23×631±12%≤0≥0≤15341±5%800PLS-YHJP-50276Φ50×Φ27×629±12%≤0≥0≤15341±5%800PLS-YHJP-603010Φ60×Φ30×1025±12%≤0≥0≤18205±5%800FOR MORE OEM SIZE WELCOME TO ENQUIRE SALERS
