Description:
ultrasonic transducer is an energy conversion device whose function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then pass it out, while it consumes a small amount of power (less than 10%). Therefore, the most important consideration for using ultrasonic transducers is the matching with the input and output terminals, followed by the mechanical mounting and mating dimensions. There are many types of ultrasonic machinery on the market, and customers must provide accurate and reliable indicators to ensure that the ultrasonic transducer products provided by the company can be matched with your company's ultrasonic machines to achieve the best performance.
The ultrasonic welding machine transducer system consists of two parts: a transducer, an amplifier (also called a horn), and the transducer is used to convert electrical signals into mechanical vibration signals and convert electrical signals into mechanical vibration signals. There are two physical effects that can be applied.
