High Power Ultra Piezoelectric Transducer with 10-12nf Capacitance
15Khz
Description:
QRsonic ultrasonic transducer uses high-quality, high-consistency
piezoelectric ceramics, professional structure design, stable
operation, high stability, high consistency, high load test,
non-hot, high amplitude, low impedance, stable wave,
Characteristics of constant waves.
Ultrasonic transducer is an energy conversion device. Its function
is to convert the input electric power into mechanical power
(ultrasound) and then transmit it out, and it consumes only a small
amount of power.

Composition:
The ultrasonic transducer is mainly composed of a central
piezoelectric ceramic element, front and rear metal cover plates,
pre-stressed screws, electrode sheets and insulating tubes. The
specific composition is shown in the figure below.
1. Rear driver: the cylindrical element on the back of the
piezoelectric transducer, the rear driver is close to the last
piece of piezoelectric ceramic, and the pre-tightening pressure is
usually applied by stacking bolts.
2. Electrode sheet: a thin conductive disc between the
piezoelectric ceramics adjacent to the transducer. The transducer
drive voltage is applied between these electrodes.
3. Front-end driver: Transmit the ultrasonic energy of the
transducer to the horn or tool head. The front-end driver usually
includes a mounting flange for connecting the housing.
4. Prestressed screw: A single stacked bolt passes through the
center hole of the ceramic. After tightening the bolt, the ceramic
will be compressed between the rear driver and the front driver to
apply the required prestress to the ceramic.
5. Piezoelectric ceramics: Piezoelectric ceramics is the heart of
the transducer, a component that converts the electrical signal of
the ultrasonic generator into linear mechanical vibration.
