Product Description

Product Description

  A 20 kHz ultrasonic transducer is an electroacoustic device that converts electrical energy into high-frequency sound waves at 20,000 cycles per second (20 kHz) or vice versa. This frequency lies at the lower end of the ultrasonic spectrum, making it ideal for industrial, cleaning, and welding applications due to its strong power output and effective material penetration.  

1.Working Principle

The 20 kHz transducer primarily operates based on the piezoelectric effect:  

- Transmission Mode: When an alternating electrical signal (at 20 kHz) is applied to the piezoelectric ceramic (e.g., PZT), it vibrates mechanically, generating ultrasonic waves.  

- Reception Mode: Conversely, when ultrasonic waves hit the transducer, the piezoelectric element generates an electrical signal for detection.  

(Note: Some high-power transducers use magnetostrictive materials, but piezoelectric types are more common at 20 kHz.)
 

2. Key Components

- Piezoelectric Element: Typically made of lead zirconate titanate (PZT), responsible for energy conversion.  

- Front Plate (Radiating Surface): Transmits ultrasonic vibrations into the medium (liquid or solid).  

- Backing Material: Absorbs backward vibrations to improve efficiency.  

- Housing: Protects internal components and provides structural support.  

 

3. Performance Characteristics

- Frequency: Fixed at 20 kHz (±1 kHz tolerance in most industrial applications).  

- Power Handling: Ranges from 50W to several kilowatts, depending on design.  

- Impedance Matching: Optimized to work with 20 kHz ultrasonic generators.  

- Efficiency: Typically 70-90% for well-designed transducers.  

- Durability: Designed for long-term operation in harsh environments (e.g., ultrasonic cleaners).  

 

4. Applications of 20 kHz Ultrasonic Transducers

     Ultrasonic Cleaning

-Used in industrial parts cleaning, jewelry, and electronics.  

-Cavitation bubbles generated by 20 kHz ultrasound remove contaminants effectively.  

 

     Plastic & Metal Welding

- Joins thermoplastics or thin metals by localized melting via ultrasonic friction.  

- Common in automotive, packaging, and electronics industries.  

 

     Sonochemical Processing

- Enhances chemical reactions in liquids (e.g., nanoparticle synthesis, wastewater treatment).  

 

5. Advantages

  Advantages:  

- High power output suitable for industrial processes.  

- Strong cavitation effect for cleaning and mixing.  

- Reliable and long-lasting in continuous operation.  

 

6. Selection Criteria  

When choosing a 20 kHz transducer, consider:  

- Power Rating  

- Impedance  

- Waterproofing (for submerged applications like cleaning)  

- Mounting Style(threaded, bolted, or flange-mounted)  

 

The 20 kHz ultrasonic transducer is a workhorse in industrial and high-power applications, offering robust performance for cleaning, welding, and chemical processes. While it lacks the precision of higher-frequency transducers, its efficiency and reliability make it indispensable in many fields.
