38*15*5mm Standard Piezoelectric Element Piezo Ceramic Ring For Use 60W Ultrasonic Transducer

Piezoelectric ceramics have a variety of different principles in the conversion process. From the current situation, the piezoelectric ceramics are basically converted effectively through the action of sound waves, and the actual conversion of these piezoelectric ceramics In the process, it will be able to generate more inductive loads, and can even be converted by the piezoelectric effect of piezoelectric ceramics. In the actual conversion, more vibrations can be generated, and more acoustic waves will be emitted. Of course Among them, the entire piezoelectric ceramic conversion also has different conversion work, and there will be more standards for use.

Piezoelectric ceramic sheet is a kind of electroacoustic device with simple structure and light weight. It has the advantages of high sensitivity, no magnetic field spreading, no copper wire and magnet, low cost, low power consumption, convenient repair, and convenient mass production. widely used. Suitable for the transmission and reception of ultrasonic and infrasonic waves. Piezoelectric ceramics with a relatively large area can also be used to detect pressure and vibration. The working principle is to use the reversibility of the piezoelectric effect. Applying audio voltage on it can generate mechanical vibration, thereby makes a sound. If pressure is continuously applied to the piezoelectric ceramic sheet, it will also generate voltage and current.
Common piezoelectric ceramics
1. Barium titanate (BaTiO3) piezoelectric ceramics have high piezoelectric coefficient and dielectric constant, and their mechanical strength is not as good as quartz.
2. Lead magnesium niobate Pb(MgNb)O3-PbTiO3-PbZrO3 piezoelectric ceramics (PMN) have a high piezoelectric coefficient and can continue to work under pressures as high as 700kg/cm2, and can be used as a force sensor at high temperatures.
3. Lead zirconate titanate Pb (Zr•Ti) O3 piezoelectric ceramics (PZT) have high piezoelectric coefficient, and various electromechanical parameters change little with external conditions such as temperature and time. Add one or two to lead zirconate titanate Kind of trace elements, PZT materials with different properties can be obtained.

The piezoelectric ceramic ultrasonic transducer is suitable for use in ultrasonic welding equipment and ultrasonic cleaning equipment. It is mainly made of high-power transmitting piezoelectric ceramics. The ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. As energy conversion device, its function is to convert the input electric power into mechanical power (ie ultrasonic wave) and then transmit it out, and it consumes a small part of the power.
