Piezo Ceramic Plate For Making Piezoelectric Vibration Sensor
The piezoelectric element has piezoelectric effect, and the
piezoelectric effect is reversible. The piezoelectric effect is
applied stress in a particular direction along certain crystal,
crystal polarization change, and change is proportional to the
called positive piezoelectric effect, on the contrary and stress
variables, an electric field on the crystal strain and strain
resulted in proportional to the electric field is called inverse
piezoelectric effect. Because of the piezoelectric effect,
piezoelectric element can force, pressure, acceleration,
temperature, quality and other non electrical quantity into
electrical quantity according to certain rules, all kinds of
sensors can be used to produce a detection, to achieve certain non
electrical quantity conversion, control and transmission function,
in the military and civil widely application. The piezoelectric
sensor is the direct use of piezoelectric effect and inverse
piezoelectric effect of piezoelectric material, the former is
charge by the piezoelectric element generated by reflecting the
size or change of measurement, which is measured by changes reflect
changes in the piezoelectric element vibration or deformation.
Piezoelectric ceramics are functional ceramic materials that can
convert mechanical energy and electrical energy to each other and
belong to inorganic non-metallic materials. At the same time, it
has a positive inverse piezoelectric effect. The piezoelectric
ceramic wafers produced are mainly used in ultrasonic probes,
ultrasonic medical instruments, ultrasonic flow meters, and
automatic control. With outstanding performance and complete
specifications, PZT piezoelectric wafers and new composite
piezoelectric wafers can meet different types of requirements
