The resonant frequency and bandwidth of ultrasonic transducers are selected from the PZT-5A piezoelectric ceramic disc polarized in the thickness direction as the transducer, and the radius R of the piezoelectric ceramic disc is 6mm and has a thickness h. The height of the outer surface of the inner

1 IntroductionWith the development of new technologies such as automation, the number of ultrasonic transducers is increasing, and all modern instruments and equipment are inseparable from sensors in the industrial production, especially in the production processes, various transducers are used to m

Ultrasonic position sensor adopts the principle of ultrasonic echo measurement. It uses different measurement technology to detect the distance between the sensor . The ultrasonic sensor with small angle and small blind area has the advantages of accurate measurement, no contact, waterproof, anti-co

The new technology of ultrasonic transducer includes a built-in temperature compensation circuit. Under the normal or changing operating conditions, when there is a significant temperature change, the temperature compensation circuit is used for proofreading; the advanced filter circuit allows the

Ultrasonic transducer are developed to use the characteristics of ultrasound. Ultrasound wave is a kind of mechanical wave whose vibration frequency is higher than that of sound waves. It is generated by transducers vibrating under the excitation of voltage. It has high frequency, short wavelengt
