What is ultrasonic transducer

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effect. A driving force is generated to cause it to vibrate, thereby propelling the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium.

ultrasonic transducer is an energy conversion device whose performance description and evaluation requires many parameters. The characteristics of the transducer include resonance frequency, frequency bandwidth, electromechanical coupling coefficient, electroacoustic efficiency, mechanical quality factor, impedance characteristics, frequency characteristics, Directivity, transmit and receive sensitivity, etc. Transducers for different applications have different performance parameters. For example, for an emissive transducer, the transducer is required to have large output power and high energy conversion efficiency; Receiver-type transducers require a wide frequency band and high sensitivity and resolution. Therefore, in the specific design process of the transducer, the relevant parameters of the transducer must be rationally designed according to the specific application.

In order to determine the operating state of the transducer, the state equation of the mechanical vibration system and the equation of state of the circuit must be obtained. The equation of state of the mechanical system of the transducer (referred to as the mechanical vibration equation) is when the transducer is in operation. Describe the relationship between the force of the mechanical vibration system and the vibration velocity, and the equation of state of the circuit system (referred to as the circuit state equation) describes the vibration characteristics of the circuit system. Since the mechanical system and the circuit system of the transducer are coupled to each other Therefore, the vibration of the mechanical system will affect the balance of the circuit, and the change of the circuit will also affect the vibration of the mechanical system. Therefore, we always use these equations to analyze and discuss the working characteristics of the transducer.

 20Khz duakne transducer




1. What’s the warranty of your transducer and equipment.

Our warranty is one year for both transducer and equipment, but we can supply you Components free even out of warranty.


2. What’s frequency transducer you supply?

We can supply transducer from 15Khz to 70Khz depending on your requirements or application.


3. What’s the using life of your transducer?

Under correct working environment, our transducer can work 5~10 years


4. What’s the using life of your generator?

Under correct working environment, our generator can work 8~10 years


5. Does your products exported before?

Yes, our transducer exported to USA,south America, EUROPE, Middle East, and Russia for many years.


6. Do you supply sample for test?

Yes, you can order on sample from our company first , we will return you the sample cost when you order in the future.


7. Do you supply OEM work?

Yes, welcome to ask for OEM cooperation , we have OEM produced for USA and German customer for many years, also hope to get more OEM order to enlarge our business.


8. how to customize transducer ?

For two ways for customize transducer, first way, you supply me sample , I will customize depending on your sample. Second, you give us all parameter and drawing , we can customize depending on your information.


9. Can you generator connect to PC, PLC or internet .

Yes, we have different version generator, it can connect to PC. PLC, even internet.Also the price different.


10. What we can get if the transducer/equipment broken during the warranty?

All our transducer and generator tested at least 48 hours before shipment , so we have confidence to our equipment. Of course, We will send you new transducer/ equipment if it broken in the warranty. At the same time, we need to find the problem , why it broken so fast.


Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.
