Ultrasonic humidifier piezoelectric transducer
SPECIFICATION FOR APPROVAL
Part No.:PZT-25-1.7BU
The company’s ultrasonic atomizing sheet uses glass glaze as the electrode protective layer. Compared with the traditional nickel-plated and titanium-plated electrode atomized sheet, it has the advantages of acid and alkali resistance, cavitation corrosion resistance, etc., which can prolong the service life of the atomizing sheet.

Precautions for use
The atomized sheet should be fastened and leveled when used;
The atomized sheet should work in an environment with water;
The surface of the atomized sheet should be cleaned regularly. Since the working liquid in the water contains Ca, Na, Mg, Si and other substances, scales are likely to occur after working for a period of time, and the amount of atomization may be decreased after the scale adheres;
When designing the circuit, ensure that there is no potential difference between the atomized sheet and water or other liquid and that the chip electrode product is electrolyzed, it is necessary to have a water-free protection circuit. A magnetic-floating switch is recommended. The atomizing sheet is strictly prohibited to work in the water. Or without other liquids;
Under no circumstances should you solder the chip connection wires yourself to avoid damage to the product;
The atomized sheet is a fragile product. Strong vibration or impact may damage the atomized sheet. Please install it carefully.
