Ultrasonic cleaning transducer

Ultrasonic Cleaning Transducers possesses low electro-acoustic conversion efficiency. after one or two years of use, the transducer’s efficiency reduces. Also, it loses most of its electro-acoustic conversion properties.

The complexity that accompanies the Nickel Plate Transducers makes them expensive and scarce. Meanwhile, the piezoelectric transducer is more reliable and less costly. The piezoelectric transducer is able to convert energy due to the piezoelectric effect.

The piezoelectric effect is responsible for converting electrical signals to mechanical vibrations. Some of the properties that set the piezoelectric transducer apart are as follows;

  • Easy of production
  • it last long
  • Low-cost of raw materials
  • High electro-acoustic conversion efficiency

Some of the common material for producing the transducer are;

  • Lead zirconate titanate
  • Quartz crystal
  • Barium titanate.

Materials and their properties

The piezoelectric effect of barium titanate is about 20-30 times bigger than the quartz crystal. However, quartz crystal edges out in terms of mechanical strength and efficiency.

Lead zirconate titanate is great for producing transducers for low-power ultrasonic processing. Likewise, it can be used in ultrasonic cleaning and flaw detection. Lead zirconate has the right balance of piezoelectric effect, mechanical strength, and efficiency.

Industries that make use of ultrasonic cleaning transducers are;

  • Military
  • Agriculture
  • Medical
  • Industrial
  • Transportation

Uses of Transducers

Manufacturing processes and material will determine the properties of a transducer. For instance, the ultrasonic cleaning transducer can convert high-frequency electrical signal. The size of a transducer will impact its service life and performance.

The ultrasonic cleaning transducers are used in the following;

Ultrasonic emulsifier homogenizers

Plastic welding machines

Hand-held ultrasonic tools

Engraving machines

Atomizers

Metal welding machines.

The popular frequencies choice for most transducer production are 15KHz, 20KHz, 28KHz, 35KHz, 55KHz, and 70KHz. Depending on the needs of the customer, other types of transducers can be produced.
