• Ultrasonic Energy Communication Parts Piezoelectric Wafer Sensor Emitter Piezo Ceramic Components Pzt44 MaterialThe principle of the piezoelectric ceramic transducer is that once stress or strain is applied to the ceramic chip, prices of contrary polarity are generated on the two ends of the ceramic chip, and a latest is generated within the process the circuit. This influence is called the piezoelectric effect. Therefore, within the design of ultrasonic transducers, different factors should be considered, akin to acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and how to design and coordinate those facets to attain electro-acoustic conversion. splendid value. As a type of calories transmission network, piezoelectric ceramic transducer has the problem of calories conversion performance conversion performance is said to the selection of the transducer material, the form 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 digital ceramic materials with piezoelectric characteristics. The main distinction from a typical piezoelectric quartz crystal that does not involve ferroelectric substances is that the main element of the crystal phase 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 fabricated from such piezoelectric ceramics is put into water, then under the motion of sound waves, charges may be brought on at both ends of the transducer, which is a valid wave receiver. In addition, the piezoelectric effect is reversible. If an alternating electric subject is applied to a piezoelectric ceramic sheet, the ceramic sheet will develop 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 display macroscopic piezoelectric properties, the piezoelectric ceramic needs to be polarized in a strong DC electrical subject after firing, and the top face is subjected to a number of electrodes, simply so the polarization vector of the original disordered orientation is preferentially orientated in the process the electrical field, and after the electrical area is eliminated , The piezoelectric ceramic after polarization medication will maintain a distinct macroscopic residual polarization strength, in order that the ceramic has a distinct pressure. Piezoelectric ceramic discs, ceramic rings, oblong piezoelectric pickups, ceramic tubes, ceramic squares, ceramic tiles, drawings of varied specifications would be customized Description:Ultrasonic strain ceramic wafer product features:1.
