How to Make an Ultrasonic Water Atomizer

Ultrasonic water atomizers work by creating a sonic vibration. The transducer which creates the vibration is placed in a liquid, usually water. The vibration agitates the surface of the water to create droplets. The droplets hit a screen and the impact creates smaller droplets that disperse into the air. Transducers can be added to humidifiers, nebulizers or are placed in a container with a lid that is either screened or has holes allowing the droplets to enter the air.

Instructions

1

Solder the transducer leads to the nebulizer board with lead-free solder. The leads connect to the board in the space labeled "TD."

2

Attach a 48-volt AC power supply to the board using the supplied connectors on the board in the area labeled "AC." Attach the wires to the connectors, without any soldering. If you prefer to use a 48 VDC power supply, solder the wires to the "D1" and "D2" spots on the "VDC" area on the board. Plug in the power supply and listen for the transducer to buzz so you can test to see if the parts are properly connected.

3

Place the ceramic transducer in the container or humidifier. The water level should be 1.18 inches. Close the cover of the container. Make sure there is a seal around the hole where the transducer leads leave the container. Plug in the atomizer. Add more water as needed when the atomizer is running.
