Ceramic Piezoelectric Element

This includes piezoceramic components and elements as well as piezoelectric actuators.

Ceramic piezoelectric element.

Piezoelectric ceramic components are electromechanical transducers. Stress on ceramic element. Certified in accordance with iso 9001 iso 14001 and ohsas 18001 pi ceramic is one of the world s market lead ers for piezoelectric actuators and sensors. We can customized various piezoelectric ceramics pzt ring piezo disc piezo plate piezo cylinder piezo unimorph piezo bimorph self drive piezo diaphram external drive piezo diaphram.

E g 33 t q d 33 f where e. Behavior of a piezo element influence of input frequency. Even if the electric fi eld is eliminated the length of the piezoelectric ceramic element does not return to its original length in the nonpolarized state as a result of the 90 inversion of the zr ion or ti ion. The variation in the length of the element is called residual polarization fig.

Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals certain ceramics and biological matter such as bone dna and various proteins in response to applied mechanical stress the word piezoelectricity means electricity resulting from pressure and latent heat. The designations of soft and hard piezo ceramics refer to the mobility of the dipoles or domains and hence also to the polarization and depolarization behavior. Equipment for ceramic production in house. Piezoelectric sensors are versatile tools for the measurement of various processes.

Pi ceramic provides a wide selection of piezoelectric ceramic materials based on modified lead zirconate titanate pzt and barium titanate. The microscopic origin of the piezoelectric effe ct is the displacement of ionic charges within a crystal struc ture. Pierre curie discovered the piezoelectric effect in 1880 but only in the 1950s did manufacturers begin to use the piezoelectric effect in industrial sensing applications. Pi ceramic offers a large number of standard products and solutions based on piezo technology.

Pzt electronic ceramic co ltd is the expert of piezo ceramics we are real manufacture with 20years experiences in this field. Electric field g 33. They are used for quality assurance process control and for research and development in many industries. Piezein which means to squeeze or.

Piezoelectric voltage constant t. Piezoelectric ceramic rectangular component. They can convert mechanical energy into electrical energy and vice versa piezoelectric ceramic components are used in a variety of electromechanical transducer in a wide frequency range piezoelectric ceramic rectangle components is a single and dextrous electrical devices with high. In the absence of external st rain the charge distribution is.

It is derived from the greek word πιέζειν.
