Advantages of Piezo Atomizing Transducers In this content, we’ll explore the advantages and disadvantages of ultrasonic piezo atomizing transducers. Piezo atomizing transducers are better suited for applications that require larger aerosols. They operate by using high-frequency vibrations to atomize the liquid, with the size of the droplets generated depending on several factors. In summary piezo atomizing transducers are used to generate fine mist or aerosols from liquids. Typically, droplet sizes range from 5-20 microns, making piezo atomizing transducers ideal for generating larger aerosols. The size of the droplets generated by a piezo atomizing transducer is also dependent on several factors, including the frequency and amplitude of the vibrations, the viscosity of the liquid, and the size and shape of the nozzle. This, in turn, creates pressure waves in the liquid, which causes the liquid to be atomized and form a fine mist. When an electric current is applied to the piezoelectric element, it vibrates, causing the diaphragm to oscillate. The transducer consists of a piezoelectric element, a diaphragm, and a liquid reservoir. However, piezo atomizing transducers operate at a higher frequency than ultrasonic nebulizers, typically in the range of 100-500 kHz. Piezo atomizing transducers use high-frequency vibrations to atomize a liquid. In this content, we’ll delve into the detailed mechanics of Ultrasonic Piezo Atomizing Transducers. The number of holes and size of holes in the mesh disc is a key factor in determining the droplet size and flow rate. ![]() ![]() The micron-size droplets produced by the atomizing transducer, or ultrasonic nebulizer, are extremely uniform in size and distribution because the mesh layer is engineered with a precise number of holes that are all a specific size. The rapid ultrasonic vibration from the atomizing transducer causes the fluid to be pushed through the mesh layer, producing tiny droplets or mist. When an electrical voltage is applied to an atomizing transducer, the piezo transducer generates ultrasonic frequencies. A perforated mesh layer with many tiny holes is placed on top of the liquid reservoir and piezo element. A fluid solution is placed in a reservoir, surrounded by a piezo element, usually a piezo disc. ![]() Let’s take a closer look at the component parts of piezo atomizing transducers. Atomizing transducers atomize liquids by using ultrasonic vibrations to push the liquid solution through a mesh layer, creating micron-size droplets.
