Tubular Piezoelectric Ceramics PZT Tube for Measurement

Piezoelectric ceramics have sensitive characteristics, which can convert extremely weak mechanical vibration into electrical signals, and can be used in sonar system, meteorological detection, remote sensing, environmental protection, household appliances and so on. Earthquake is a destructive disaster, and its source begins in the deep crust, which is difficult to predict before, which makes human beings in an awkward situation. Piezoelectric ceramics are sensitive to external forces, so that it can even sense the air disturbance caused by flying insects flapping their wings more than ten meters away. Using it to make piezoelectric seismograph can accurately measure the earthquake intensity and indicate the direction and distance of the earthquake. This can not be said to be a great work of piezoelectric ceramics.

 

In terms of energy conversion, piezoelectric igniter, mobile X-ray power supply and shell detonating device can be manufactured by using the characteristics of piezoelectric ceramics to convert external force into electric energy. In electronic lighters, there are flints made of piezoelectric ceramics, and the number of fires can be more than 1 million. Using piezoelectric ceramics to convert electrical energy into ultrasonic vibration can be used to explore the position and shape of underwater fish, nondestructive testing of metals, ultrasonic cleaning and ultrasonic medical treatment. It can also be made into various ultrasonic cutters, welding devices and soldering irons to process plastics and even metals.
