320KHZ PZT-4/pzt-8 Piezo Ceramic Disk Ultrasonic Distance Sensor
In industry, there are piezoelectric ceramic elements in the geological detector, which can be used to judge the geological conditions of the strata and find out the underground mineral deposits. There is also the transformer in the TV, the voltage ceramic transformer, which is smaller in volume and lighter in weight, with an efficiency of 60% - 80%. It can withstand the high voltage of 30000 volts, keep the voltage stable, and completely eliminate the defects of the fuzzy deformation of the TV image. A buzzer made of piezoelectric ceramics is installed in the belly of the toy dog, and the toy will make a vivid and interesting sound. Application in automobile: a simple piezoelectric ceramic actuator is installed in the brake piston of the automobile, which applies "shaking" frequency to the support plate of the internal brake block to effectively suppress the vibration generating sharp noise, so as to play a role in the case of temperature and humidity changes and normal wear of the brake system. Piezoelectric ceramics can also be used as piezoelectric ceramic knock sensors, ultrasonic sensors, acceleration sensors and other categories. At present, the application of piezoelectric ceramics in fuel injector of automobile fuel system is at the forefront of development stage.
