• Factory Manufacture Piezo Ceramic Ship 38*15*5mm Ultrasonic Cleaner Vibartor Ring Wafer 28K/40KThe principle of the piezoelectric ceramic transducer is that once stress or strain is applied to the ceramic chip, prices of contrary polarity are generated at the two ends of the ceramic chip, and a latest is generated in the course of the circuit. This impact is known as the piezoelectric effect. Therefore, within the design of ultrasonic transducers, different factors ought to be considered, similar to acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and the way to design and coordinate those factors to realize electro-acoustic conversion. high quality value. As a kind of energy transmission network, piezoelectric ceramic transducer has the problem of calories conversion efficiency conversion functionality is said to the choice of the transducer material, the form of vibration, the constitution of the mechanical vibration formulation (including the aid mechanism), and the working frequency. Therefore, the issue of the ultrasonic transmitter is solved. There are two supplies for piezoelectric ceramic transducers: magnetostrictive metal and piezoelectric ceramics. Piezoelectric ceramic transducer is an electronic ceramic supplies with piezoelectric characteristics. The leading distinction from a standard piezoelectric quartz crystal that doesn't involve ferroelectric elements is that the key aspect of the crystal section is all ferroelectric crystal grains. Ceramics are polycrystalline aggregates with randomly oriented grains, so the spontaneous polarization vector of each ferroelectric grain also is disoriented a transducer product of such piezoelectric ceramics is put into water, then beneath the motion of sound waves, expenses will be triggered at both ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric affect is reversible. If an alternating electric field is applied to a piezoelectric ceramic sheet, the ceramic sheet will change 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 powerful DC electric field after firing, and the top face is subjected to several electrodes, just so the polarization vector of the original disordered orientation is preferentially oriented in the process the electric field, and after the electric subject is removed , The piezoelectric ceramic after polarization remedy will maintain a certain macroscopic residual polarization strength, just so the ceramic has a definite pressure. Piezoelectric ceramic discs, ceramic rings, rectangular piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of varied specifications can be personalized Description:Ultrasonic pressure ceramic wafer product features:1.

Low calorific charge The piezoelectric ceramic ultrasonic transducer is appropriate for ultrasonic welding equipment and ultrasonic cleansing equipment. It is particularly made from high-power transmitting piezoelectric ceramics. The ultrasonic transducer is a tool that may convert high-frequency electricity into mechanical energy. As an calories conversion device, its operate is to transform the input electric power into mechanical strength (ultrasound) after which transmit it out, and it consumes a small a part of the flexibility by way of itself(mm)Radial frequency(KHz)Capacitance(pf)Dielectric dissipation factortanδ(%)Electromechanical coupling coefficient(Kr)ImpedanceZr(Ω)Thickness frequency(KHz))Mechanical positive 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
