Ultrasonic atomization is a physical process in which liquid is crushed and torn into small droplets by the energy of ultrasonic oscillation. In principle, ultrasonic atomization can be roughly divided into three types: single piezo type, mesh type and Langevin transducer type. The common ultrasonic atomization in the market refers to single piezo type and mesh type. And the single piezo type is more common one. It atomizes the liquid by the sound field produced by the vibration of piezoelectric ceramic directly immerged in the liquid. This type of atomization has the advantages of fine atomization particles and long lifetime. Typical applications include ultrasonic humidifier, aromatherapy machine, disinfection machine, etc. To learn more knowledge about ultrasonic atomization, please see the article ‘Ultrasonic Atomization’.
Ultrasonic atomizer transducer is the core component of single piezo type ultrasonic atomization. As one of the earliest enterprises to manufacture ultrasonic atomizer transducers in China, Siansonic launched patented ultrasonic atomizer transducer with nickel plating as early as the early 1990s. With excellent atomization performance and durability, Siansonic atomizer transducer has been selected by hundreds of companies in the world, and the cumulative sales has exceeded 10 million pieces. The resonant frequency of up to 3MHz can provide ultrafine atomized droplets of only 1 micron. The unique protective coating technology can realize the dual protection against both chemical corrosion and electric corrosion, so as to atomize various liquids. In addition, the ultrasonic atomizer transducer using high-intensity focused ultrasound （HIFU） technology can improve the energy conversion efficiency and is suitable for the development of atomization device driven by low voltage and low power.
Frequency: 1.7MHz, 2.0MHz, 2.4MHz, 2.5MHz,3.0MHz
Transducer: Regular, HIFU
Coatings: Nickel, Titanium alloys, Anti-corrosion
Accessory: Wires, Connector, Gasket, Housing
The transducers should NEVER work without liquid in contact with them even though in a very short time (a few seconds). Recommend to provide a protective “low liquid” shut-off circuit.
Make sure no voltage difference appears between surface of transducer and water. We highly recommend the float switch for liquid level control. PLEASE DON’TUSEELECTRODECONTROL FOR “LOW WATER” PROTECTION! OTHERWISE THE TRANSDUCER COATING CAN BE ELECTROLYZED OUT.
Transducers (except the anti-corrosion model) should work in drinking water or similar liquids. If liquids have an acidity of less than pH5, it could make the output performance decay, even permanently destroy the transducer. Therefore, if the liquid is strong acid (PH<5), you should select anti-corrosion model or contact us for technical suggestions.
The surface of transducers should be cleaned at times. It will NOT be considered as the quality problem on transducers, if the atomizing effect of transducers decays due to substances contained in liquid such as Ca, Na, Mg and Si etc. adhering to the transducers surface.
