Piezoelectric Transducers FAQs

Below are Ultrasonic Transducers for Cleaning frequently asked questions and their corresponding answers.

Do you have a catalog of Ultrasonic Transducers you produce ?

Yes ! Download Ultrasonic Cleaning Transducer Product Quotation Document. You can also learn more about Ultrasonic Transducer Technical Specification. Ultrasonic Transducers are tailor made to very specific customer requirements. Our products have been utilized in a wide spectrum of applications ranging from military to industrial to commercial. We specialize in developing ultrasonic transducers that have higher sensitivity and ring-down than similar ceramic designs.

Ultrasonic Cleaning Transducer

Can you manufacture Ultrasonic Transducers according to customers’ needs?

Our sophisticated manufacturing abilities allow us to produce designs our customers provide, regardless of whether these designs include conventional piezo composite components as active elements. Since our field of specialization is in ultrasonic transducers, we are far better than our competitors in meeting ultrasound transducer manufacturing requirements, deadlines and cost budgets. This allows our customers to save valuable time and money by outsourcing their ultrasonic transducer requirements to us.

We also facilitate our customers by providing sales packages on economies of scale, which further drive down the costs for our customer. Besides component supply, our firm also actively involves customers in our next generation designs to ensure our future line of products continue to meet their requirements effectively and efficiently.

What frequency operating ranges do you recommend ?

Ultrasonic Transducers typically operate in a frequency range of 17 kHz to 2 MHz. However, for best results, we recommend operating the transducers within 50 kHz to 1 MHz.

What are the cleaning frequencies of Ultrasonic Transducers ?

It depends on the cleaning requirements. Different frequencies are used for different kinds of cleanings, as some frequencies are better at breaking down and clearing certain particles than others. Frequencies below 80 kHz are used in cleaning components that are rugged and have heavier contaminants on them. Frequencies above 80 kHz are for more delicate components that have smaller contaminants that must still be removed as cleaning requirements are high.

You can use different frequencies on the same components to get the best cleaning results. The lower frequencies will break down the heavier components while the higher frequencies clear out the smaller particles. Make sure beforehand, however, that it’s safe to expose the components to be cleaned to the frequencies you use.

Typically, exposure to lower frequencies ultrasonic is what can cause damage. So to conduct a broad spectrum cleaning to clear out all kinds of contaminants, we recommend using lower frequencies from 40 kHz to 72 kHz for short amounts of time and higher frequencies from 104 kHz to 170 kHz for longer amounts of time. This will prevent any damage to components while ensuring all kinds of contaminants will be removed during cleaning.

How to connect multiple ultrasonic transducers ?

Transducers are to be connected in parallel.

Ultrasonic Transducer Bonding Process ?

  1. The Ultrasonic transducers are stuck to platforms using Epoxy glue.
  2. Select glue that has non-existence shrinking and thermal expansion properties. This will both reduce the stress caused by gluing and improve the reliability of the oscillator. Epoxy A and B satisfy this requirement.
  3. Sun blasting process selected by adhesive surface greatly increases adhesive strength.
  4. To clean the cemented surface, use a cleaning solvent like absolute alcohol or acetone.
  5. When carrying out the nail bonding process, take care during vertical correction when planting the nail.
  6. Take care during the adhesive curing process about the size of pre-loaded stress and consistency control.
  7. To reduce Impedance of oscillator and increase electro-acoustic output, you need to establish impedance control technology during the glowing process.
  8. You can improve the load distribution of energy by setting up impedance testing techniques for the post gluing process.
  9. Take care of three fundamental requirements: softness of wiring, strength of insulation and reliability of welding.
  10. Test the insulation after installing the wiring of the oscillator to check for any defects as an error here can have critical consequences.
  11. Carry out debugging within a temperature range of 40-50 ℃ but during operations, maintain a temperature below 80 ℃.

What are Characteristics of Pzt series and their applications ?

  1. The Pzt8 is for use in high power applications like cleansing and welding transducers. This is owing to its better thermal stability and lower heating.
  2. The Pzt4 are for use where thermal stability is a pressing requirement. The pzt4 series offers higher Curie temperature, better stability and temperature control.
