Datasheet

PZT4 Piezoelectric Ceramic Ring 20x10x4mm for sale

This is a special custom piezo ceramic ring size, Normal piezo ring transducer similar with it 25x10x5mm.

Advantages: Piezoelectric ceramic rings are characterized by small size and thinness, resistance to vibration, not being easy to damage, easy to use, high sensitivity.

What is the difference between Norvis PZT rings and other manufacturers?

At present, the inner and outer sides of the piezo ceramic ring of the transducers on the market are equipped with silver layers, which are respectively used as the positive and negative electrodes of the piezo ceramic ring. During use, the pzt ceramic ring vibrates radially, and will Wires are welded to the silver layer, which makes the silver layer on the inner and outer surfaces of the pzt4 ceramic ring easily fall off partly or completely, causing an uneven electric field on the surface of the silver layer, lowering of the insulation level and uneven vibration of the piezoelectric ceramic ring, which may easily lead to the pzt4 ceramic ring Fragmentation affects the overall life of the piezoelectric ceramic ring.

Because the material of the piezo ceramic ring is fragile, and the inner silver layer is located inside the piezo ceramic ring, when the ceramic ring vibrates radially, the inner side of the ceramic ring will shrink toward the center of the piezoelectric ceramic ring. With the above characteristics, when protecting the inner silver layer of the piezoelectric ceramic ring, not only the protection problem must be considered, but also the influence of the protection device on the conductivity of the silver layer and the influence of the structure of the protection device on the piezoelectric ceramic ring. Therefore, protect the inner silver layer The protection of it is relatively difficult.

Norvis PZT rings silver layer adhesion is very good, long service life, your best choice.
