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

The main components of the high frequency ultrasonic transducers are an outer casing, a matching layer, that is, 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, transducers, metal rings, and rubber gaskets.

2.Ultrasonic transducers, What are the specifics for the common types?

For ultrasonic transducers, there are some specific ones in common types. If divided by frequency, there are two common specifications of 28KHZ 50W and 40KHZ 50W. If divided by shape, there are two common types of column type and horn type.

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

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

4.Ultrasonic transducer, how does it emit ultrasound?

In the piezoelectric ultrasonic transducer, the main components are three 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.
