• Factory Sale Piezo Ceramic Material Pzt4 Ultrasonic Sensor Piezoelectric Wafer 38x15x5mmThe principle of the piezoelectric ceramic transducer is that once pressure or stress is applied to the ceramic chip, expenses of opposite polarity are generated at the two ends of the ceramic chip, and a latest is generated during the circuit. This effect is named the piezoelectric effect. Therefore, in the design of ultrasonic transducers, different factors must be considered, resembling acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and the way to design and coordinate those factors to attain electro-acoustic conversion. very best value. As a kind of calories transmission network, piezoelectric ceramic transducer has the problem of energy conversion efficiency conversion performance is related to the choice of the transducer material, the form of vibration, the constitution of the mechanical vibration method (including the aid mechanism), and the working frequency. Therefore, the difficulty of the ultrasonic transmitter is solved. There are two supplies for piezoelectric ceramic transducers: magnetostrictive steel and piezoelectric ceramics. Piezoelectric ceramic transducer is an digital ceramic materials with piezoelectric characteristics. The leading distinction from a typical piezoelectric quartz crystal that doesn't contain ferroelectric elements is that the foremost ingredient of the crystal phase is all ferroelectric crystal grains. Ceramics are polycrystalline aggregates with randomly oriented grains, so the spontaneous polarization vector of each ferroelectric grain is also disoriented a transducer product of such piezoelectric ceramics is put into water, then under the motion of sound waves, charges would be caused at both ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric impact is reversible. If an alternating electrical area is applied to a piezoelectric ceramic sheet, the ceramic sheet will grow to be thinner and thicker from time to time, and it's going to vibrate and emit sound waves. In order to make the ceramic show macroscopic piezoelectric properties, the piezoelectric ceramic ought to be polarized in a strong DC electrical area after firing, and the end face is subjected to several electrodes, so that the polarization vector of the original disordered orientation is preferentially orientated within the course of the electric field, and after the electric area is removed , The piezoelectric ceramic after polarization remedy will hold a distinct macroscopic residual polarization strength, simply so the ceramic has a distinct pressure. Piezoelectric ceramic discs, ceramic rings, oblong piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of various specifications can be customized Description:Ultrasonic stress ceramic wafer product features:1.

Low calorific price The piezoelectric ceramic ultrasonic transducer is suitable for ultrasonic welding package and ultrasonic cleaning equipment. It is principally manufactured from high-power transmitting piezoelectric ceramics. The ultrasonic transducer is a tool that may convert high-frequency electrical energy into mechanical energy. As an energy conversion device, its function is to convert the enter electric power into mechanical strength (ultrasound) and then transmit it out, and it consumes a small a part of the ability through itself(mm)Radial frequency(KHz)Capacitance(pf)Dielectric dissipation factortanδ(%)Electromechanical coupling coefficient(Kr)ImpedanceZr(Ω)Thickness frequency(KHz))Mechanical quality element (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
