Round piezo electric ceramicP4 / P5/ P8 disk ring element
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.
