High Power 28khz Pzt4 Ultrasonic Piezoelectric Transducer for Ultrasonic Cleaning Tank

The ultrasonic transducer is the core device of the ultrasonic equipment, and the choice of its characteristic parameters determines the performance of the whole equipment. The correct choice of the ultrasonic transducer can make your measurements more accurate. Let’s talk about how to choose an ultrasonic transducer today?

1. Understand the purpose of ultrasonic equipment

Understand your needs, understand the purpose of the ultrasonic equipment, and understand the characteristics of the required ultrasonic transducer: such as range size, corrosion protection, explosion protection.

2. Select the frequency of the ultrasonic transducer

The frequency of the ultrasound affects the propagation of the ultrasound, and different ultrasonic devices have different requirements for the frequency, which is typically between 0.5 MHz and 2 MHz when used for flow measurements. The higher the frequency of the ultrasound, the more concentrated the energy, and the better the directionality, but the higher the frequency, the greater the attenuation of the ultrasound.

3. Select the angle of incidence of the ultrasonic transducer

The angle of incidence determines where the ultrasonic transducer is mounted, and in order to ensure the selectivity of the probe in receiving the signal, it is chosen that the angle of incidence is greater than the first frontage angle and less than the second critical plane angle, with one angle between 28.7 ° and 60 °.
