Working principle of ETPU (Electronic Transistor PressureUltrasonic) machines can be explained by understanding its core components and how they interact to create ultrasonic waves.

Firstly, an ETPU machine typically consists of two main parts: a transducer, which converts electrical signals into mechanical vibrations, and a pressure sensor, which measures the pressure in the system. The transducer acts as a wave generator, emitting ultrasonic waves that propagate through the fluid medium.

The pressure sensor measures the change in pressure as the ultrasonic waves pass through it. This measurement serves as a feedback mechanism for adjusting the output frequency and amplitude of the generated ultrasonic waves.

In summary, the working principle of ETPU machines involves the use of electronic transducers to generate ultrasonic waves at specific frequencies based on the pressure input from a pressure sensor. The combination of these two elements allows for precise control over the physical properties of fluids, making them ideal for applications such as cleaning, sterilization, and other industrial processes requiring highpressure, highvelocity fluid flow.
