With regard to ultrasonic transducers, ultrasonic transmitting and receiving circuits are devices for converting electrical energy and acoustic energy. Generally, the ultrasonic transducer has low electromechanical energy efficiency, which seriously affects the working distance of the ultrasonic tra

Output function All series of ultrasonic sensors have a switch output type. Some products also have 2 switching outputs (such as minimum and maximum level control). Most products offer either analog currents or analog voltage output. Noise suppression, metal knocking, roaring and other noises do not

Researching on acoustic transducer layer materials began in the 1980s. In 1998, Kim Yeonbo and Roh Yongrae uses the method of time domain analysis to theoretically give a suitable for broadband, it is high energy ultrasound structure of the energy device and the best acoustic impedance matching valu
