25Khz Ultrasonic Converter Two Ceramics For Welding Machine Waterproof

Description:

A transducer is a device that converts electrical energy and sound energy into each other. Used in echo sounders, Doppler logs and acoustic correlation logs. Converting electrical energy into sound energy is called a transmitting transducer; converting sound energy into electrical energy is a receiving transducer. The transmit and receive transducers are usually used separately, but one can also be shared. The main performance indicators of the transducer are: operating frequency, frequency bandwidth, electro-acoustic frequency, impedance at resonant frequency, directivity (transmission beam width) and sensitivity. According to the different physical properties and materials used, transducers can be divided into two categories: magnetostrictive transducers and electrostrictive transducers. The former applies the magnetostrictive effect of ferromagnetic materials, and is often made of nickel or nickel-iron alloy; the latter applies the electrostrictive effect and piezoelectric effect, and is often made of dielectric materials such as barium titanate ceramics and milling lead titanate ceramics. . The transducer is installed on the bottom of the ship, and its directivity can be characterized by beam width or half-spread angle.
