• 38x15x5MM Size Ring Ceramic Piezoelectric Components Ultrasonic Cleaning Sensor Lead Zirconate Titanate MaterialThe principle of the piezoelectric ceramic transducer is that after strain or pressure is applied to the ceramic chip, fees of contrary polarity are generated on the two ends of the ceramic chip, and a current is generated through the circuit. This effect is called the piezoelectric effect. Therefore, in the design of ultrasonic transducers, different factors must be considered, corresponding to acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and the way to design and coordinate those features to realize electro-acoustic conversion. supreme value. As one of those energy transmission network, piezoelectric ceramic transducer has the difficulty of calories conversion performance conversion performance is asserted to the choice of the transducer material, the shape of vibration, the constitution of the mechanical vibration system (including the aid mechanism), and the operating frequency. Therefore, the problem 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 supplies with piezoelectric characteristics. The leading difference from a typical piezoelectric quartz crystal that does not involve ferroelectric elements is that the largest element 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 made from such piezoelectric ceramics is put into water, then beneath the motion of sound waves, costs might be brought on at either ends of the transducer, which is a legitimate wave receiver. In addition, the piezoelectric impact is reversible. If an alternating electrical discipline is applied to a piezoelectric ceramic sheet, the ceramic sheet will develop into 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 ought to be polarized in a powerful DC electrical discipline after firing, and the tip face is subjected to a number of electrodes, in order that the polarization vector of the original disordered orientation is preferentially oriented within the route of the electrical field, and after the electric field is eliminated , The piezoelectric ceramic after polarization medication will keep a definite macroscopic residual polarization strength, in order that the ceramic has a distinct pressure. Piezoelectric ceramic discs, ceramic rings, rectangular piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of various specifications could be custom-made Description:Ultrasonic strain ceramic wafer product features:1.

It is mainly made of 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 transform the enter electric power into mechanical energy (ultrasound) after which transmit it out, and it consumes a small a part of the power via itself(mm)Radial frequency(KHz)Capacitance(pf)Dielectric dissipation factortanδ(%)Electromechanical coupling coefficient(Kr)ImpedanceZr(Ω)Thickness frequency(KHz))Mechanical quality ingredient (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
