Ring Shape Piezoceramic Materials P4 Or P8 For Ultrasonic Sensor Using
Piezoelectric ceramic materials are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa. Piezoelectric ceramic material from us are used in sensors, actuators, gas ignition and in power transducers for high-power ultrasonic applications.

3. Is there a possibility of using piezoceramic actuators at cryogenic temperatures?
The answer is yes. From down to zero degrees Kelvin, allpiezo actuators continue to function even though it may appear counter-intuitive. Since electric fields cannot be changed by temperature at all and the inter-atomic electric fields are the basis for the piezoelectric effect, the most common piezoceramics does decrease due to piezo coupling as temperature drops. Most importantly the motion of most materials drops to about one-seventh of that measured at room at liquid helium temperatures.
Established in 1999, Beijing Cheng-cheng Weiye Science and Technology Co., Ltd is a professional manufacturer in ultrasonic transducers, ultrasonic equipment and piezoelectric ceramics.
Notably in 2004, we researched and developed our ultrasonic tubular transducer equipment into a new product that turns the extreme inconvenience brought about by pipeline and vacuum cleaning into an easy task. This product has been widely used in distillation, mix and mill for various chemical procedures and has received much praise from our customers.
