• Pzt8 Type Ultrasonic Ceramic Ring Welding Sensor Piezoelectric Element Round Ceramic Material 40mm DiameterThe precept of the piezoelectric ceramic transducer is that when stress or tension is utilized to the ceramic chip, prices of contrary polarity are generated at the two ends of the ceramic chip, and a recent is generated during the circuit. This impact is known as the piezoelectric effect. Therefore, within the design of ultrasonic transducers, different factors should be considered, corresponding to acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and the way to design and coordinate these points to realize electro-acoustic conversion. supreme value. As a type of calories transmission network, piezoelectric ceramic transducer has the difficulty of energy conversion performance conversion functionality is expounded to the choice of the transducer material, the shape of vibration, the constitution of the mechanical vibration components (including the help mechanism), and the working frequency. Therefore, the problem of the ultrasonic transmitter is solved. There are two supplies for piezoelectric ceramic transducers: magnetostrictive steel and piezoelectric ceramics. Piezoelectric ceramic transducer is an electronic ceramic materials with piezoelectric characteristics. The leading distinction from a standard piezoelectric quartz crystal that doesn't involve ferroelectric elements is that the foremost factor of the crystal part is all ferroelectric crystal grains. Ceramics are polycrystalline aggregates with randomly orientated grains, so the spontaneous polarization vector of every ferroelectric grain is also disoriented a transducer made of such piezoelectric ceramics is put into water, then beneath the action of sound waves, costs will be brought about at either ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric impact is reversible. If an alternating electric area is utilized to a piezoelectric ceramic sheet, the ceramic sheet will develop to be thinner and thicker from time to time, and it is going to vibrate and emit sound waves. In order to make the ceramic exhibit macroscopic piezoelectric properties, the piezoelectric ceramic needs to be polarized in a strong DC electric field after firing, and the tip face is subjected to several electrodes, in order that the polarization vector of the original disordered orientation is preferentially oriented in the process the electric field, and after the electrical subject is removed , The piezoelectric ceramic after polarization medication will keep a definite macroscopic residual polarization strength, in order that the ceramic has a undeniable pressure. Piezoelectric ceramic discs, ceramic rings, rectangular piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of various specifications can be custom-made Description:Ultrasonic pressure ceramic wafer product features:1.

It is mainly fabricated 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 transform the enter electrical energy into mechanical power (ultrasound) and then transmit it out, and it consumes a small part of the flexibility by means of technique of 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
