Two important properties involved in parts cleaning are viscosity and surface tension. Understanding these concepts is useful for determining what cleaning methods will be most effective for an application. What is Viscosity? Viscosity is a physical characteristic of fluids that demonstrates resistance to motion or flow. Water is an example of a low viscosity (thin) … Continued

There are two fundamental transducer designs used for power ultrasonic applications today, magnetostrictive and piezoelectric. Piezoelectric transducers utilize the piezoelectric property of a material to convert electrical energy directly into mechanical energy. Magnetostrictive transducers utilize the magnetostrictive property of a material to convert the energy in a magnetic field into mechanical energy. The magnetic field … Continued

There are many ways to alter the characteristics of ultrasonic waves in a liquid contained in a tank. The ultrasonic waves can be frequency modulated (FM) by varying the output frequency of the ultrasonic generator. The ultrasonic waves can be amplitude modulated (AM) by changing the amplitude of the generator output and/or by tailoring the … Continued
