Ceramic Transducer Design

A composite transducer consisting of several small piezo ceramic rings oscillates in resonance at frequencies between 20 khz and 80 khz.

Ceramic transducer design.

Almost all piezo ceramic transducers are supplied with an integral quarter wave matching layer to effectively couple the high characteristic acoustic impedance of piezo ceramics typically in excess of 30 mrayls into the 1 5 mrayls load that is presented by water. Find high quality ceramic transducer design suppliers on alibaba. Ctdco formerly ceramic transducer design co ltd is a leading manufacturer and supplier of piezoelectric transducer and ultrasonic sensor to domestic and international companies. Download the datasheet pdf.

Most precision acoustics. It is an encapsulated piezoelectric ceramic tube. So in air the transducer displays the same resonance modes as the unencapsulated ceramic tube. This causes a small scalpel blade in a medical tool to vibrate allowing the surgeon to perform minutely small very precise cuts using substantially less cutting force and without damaging surrounding tissue.

To create piezoelectric ceramics polycrystalline ceramics are fired and baked at a high temperature. Such sensors are used in equipment and mechanical engineering and plant construction. Reveal patterns in global trade. Alibaba offers 26 ceramic transducer design suppliers and ceramic transducer design manufacturers distributors factories companies.

Ceramic transducer design co ltd ctdco is a professional manufacturer of ultrasonic sensor and piezoelectric transducer in taiwan for over 25 years. Since its establishment in 1990 it have pursued research and development the elements only in taiwan. To obtain a quotation fill in transducer design questionnaire below. The free flooded ring is a simple design.

The transducer was able to satisfy all of the beyond the state of the art specifications and its weight and price were approximately one half that of the non conforming previous designs. Then electrodes are mounted and a dc field applied in order to polarize the ceramic material. Request a demo 1 min video. We don t offer the finished product with the pcb in the market.

Top countries regions supplied by ceramic transducer design co ltd. During the mid 1950s a proprietary ceramic transducer design was developed by massa products corp for use on the sqs 23 sonar. A piezo ceramic transducer emits a short ultrasonic pulse which is reflected by an obstacle before being received again by the same piezo transducer. See ceramic transducer design co ltd.

The distance between the transmitter and the obstacle can be calculated from the beam transit time. There are 17 oem 16 odm 4 self patent. In water however an additional resonance mode occurs.
