What is the piezoelectric effect of crystal?
Piezoelectric effect of crystal, Crystals with piezoelectric
properties are collectively called piezoelectric crystals, when a
force is applied in the right direction, the state of the electric
polarization inside the crystal changes, and on the facing side of
the crystals, it will appear bound charge with opposite signs,
which is in proportional to the external force. This phenomenon of
giving electricity to crystals in the means of external force is
called the piezoelectric effect. On the contrary, if add an
external electric field to the piezoelectric crystals, the electric
polarization inside the changes accordingly, and will thus generate
a phenomenon of strain that is proportional to the external
electric field intensity, this is what we called the inverse
piezoelectric effect. Those two piezoelectric effects are very
frequently used, one is that the distortion direction coincides
with the electric field, known as the longitudinal piezoelectric
effect, another is that the distortion direction is perpendicular
to the electric field, known as the transverse piezoelectric
effect.

FAQ:
Q: What is the service time of the transducer?
A: General speaking, it depends on the quality of the transducer.
All of our transducers are highly processed and adopt superior PZT
ceramics. The lifetime will be more than 5years.
Q: What is the structure of the PZT transducer?
A: The transducer consists of a housing, a matching layer, a
piezoceramic disc transducer, a backing, an outgoing cable, and a
Cymbal array receiver.
Q: What is the lifetime of the transducer?
A: General speaking, it depends on the quality of the transducer.
All of our transducers are highly processed and adopt superior PZT
ceramics. The lifetime will be more than 5years.
Q: What are 1/2-20UNF means?
A: It is a kind of American thread code, 1/2 means 1/2 inch of the
diameter, and 20 means there are 20 threads per inch.
