Ultrasound transducer Piezo Ceramic Ring 35x15x5mm
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 ceramic wafer is a simple and lightweight electrical device. It is widely used because of its high sensitivity, no magnetic field spreading, no copper wire and magnet, low cost, low power consumption, and easy mass production. Suitable for the transmission and reception of ultrasonic and infrasonic waves, a relatively large area of piezoelectric ceramics can also be used to detect pressure and vibration. The working principle is to use the reversibility of the piezoelectric effect to apply audio voltage on it to emit sound
