Transducer characteristics and calibration methodsA hydroacoustic transducer is a device that converts acoustic energy and electrical energy each other. The position in sonar is similar to the antenna in a radio, an acoustic system that emits and receives sound waves in seawater. A piezoelectric tra

71% of the earth's surface area is the ocean. The ocean contains abundant biological and mineral resources, which is the second space for human survival and development in the future. Sonar is used for an underwater detection device, is an important helper for human development of the ocean, and is

A ultrasonic transducer is a device that converts mechanical vibration into electrical signals or mechanical vibrations driven by an electric field. Piezoelectric polymer electroacoustic devices utilize the transverse piezoelectric effect of the polymer, while transducer design utilizes polymer piez

Ultrasonic sensor detection technologyThe ultrasonic transducers are a piezoelectric ceramic device that realizes bidirectional conversion of mechanical energy and electrical energy through a piezoelectric effect. Its propagation speed is 344m / s (25 degrees). The operating frequency is generally b

3. Classification of ultrasoundUltrasonic waves carry information about the fluid flow rate as they propagate through the flowing fluid. Therefore, the flow rate of the fluid can be detected by the receiving ultrasonic wave, and converted into a flow rate. According to the detection method, it can b
