Performance and frequency of ultrasonic transducer

1.What’s the common method for measuring the speed of ultrasonic transducers?

Among the method about measuring speed of Ultrasonic distance measuring transducer, a resonance method is commonly used, transducers emit similar sound wave of plane wave and then reflected and superimposed by the sound wave between the end faces after being reflected by the receiver, thereby , It forms a resonance standing wave phenomenon. The speed of sound of the ultrasonic transducer is measured by the change of the electrical signal and the distance between the resonant positions.

2. Ultrasonic transducer, what kind of device is it? Is there a piezoelectric ceramic in this device?

An ultrasonic transducer is a device that converts high frequency electrical energy into mechanical energy. In terms of specific types, there are generally two types of magnetostrictive and piezoelectric ceramic. As for the composition, it is certain to have piezoelectric ceramics, so that the distance transducer for parking sensor can work normally. 

3.Ultrasonic transducer, how can it be understood? For the 60W and 100W ultrasonic transducers, what is the difference between them?

The understanding of ultrasonic transducers can also be considered as an energy conversion device, because there is a energy transition during operation, As for the main difference between the 60W and 100W long range distance measuring transducer is power and capacity.

4. What is the resonance state of the ultrasonic transducer? Under what conditions can it be converted into ultrasonic vibration?

   Specifically, the resonant state of the ultrasonic transducer means that the operating state is at the resonant frequency point of the transducer. In addition, about the ultrasonic transducer, the ultrasonic vibration must satisfy the condition is to apply an 200 kHz?working voltage of ultrasonic sensor .

5. Ultrasonic transducers, which are the main components? What are its characteristics?

  The main components of the ultrasonic transducer are an shell, an acoustic window, a piezoelectric ceramic disk transducer, a backing, and an extraction cable. Its main feature is that it also includes an array receiver. For array receivers, there are lead cables, underwater acoustic transducer, metal rings, and rubber gaskets.

6. What is the frequency and nominality of ultrasonic transducer? How can the resonant frequency be obtained?

  For depth measurement ultrasonic transducer, the frequency of which refers to the maximum power of the transducer. The nominal value is mainly the voltage, which refers to the upper limit voltage value. If it is exceeded, the ultrasonic transducer will be damaged. In addition, the acquisition of its frequency can be obtained by using an impedance analyzer or by actual measurement.

7. Ultrasonic transducer, how does it emit ultrasonic waves?

In the dual frequency depth measurement transducer, the main components are piezoelectric ceramic wafers, an oscillating circuit and a resonant impedance matching circuit. The high frequency electric signal is generated by the oscillating circuit, and the piezoelectric ceramic wafer is driven by the resonant impedance matching circuit to vibrate, so that ultrasonic waves can be generated.
