Based on the pressure resistance of piezoelectric ceramic spherical shell itself, a pressure-resistant.hydrophone was designed and fabricated by using radially poled air backing piezoelectric ceramic spherical shell.transducer as acoustic sensitive element. Firstly, the acoustic characteristics such

Research progress of deep water transducers Deep-sea space is the new commanding heights of current maritime military competition. One of my country's marine strategic goals is to move toward deep blue. The development of deep-sea acoustic equipment promotes continuous breakthroughs in deep-water t

The underwater acoustic transducer is the main tool that uses sound waves to detect, identify and locate underwater targets, or to communicate and send reports underwater. The transducer is used to emit sound waves is called a transmitter. When the transducer is in the emitting state, it converts el

Acoustic waves are considered to be the only information carrier that can travel long distances in the ocean. Marine research, resource development, and maritime military struggles are all inseparable from underwater acoustic technology. The development of hydroacoustic technology requires various t

Objective To study the changes in the shape and geometrical position of the acoustic focal range of the concave spherical ultrasonic transducer when the sound intensity is high and the medium has a large attenuation. Methods From the perspective of physical acoustics, the effects of nonlinearity and

According to customer’ needs, we can design and produce piezoelectric ultrasonic transducers, underwater acoustic transducer ,ultrasonic probes and sensors of various frequencies with stable performance and high quality.

Low frequency, deep water, high power transducer Low-frequency transmitting transducer series: There are various types of flexural transducers, slotted circular tube transducers, slat bending transducers, combined bending disc transducers, etc. The minimum operating frequency has been as low as 20Hz

Ultrasonic distance transducers are sensors developed using the characteristics of ultrasonic waves. Ultrasonic is a mechanical wave with a higher vibration frequency than sound waves. It is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, sho

Ultrasonic waves propagate in a straight line. The frequency is the higher , the diffraction ability is the weaker, but the stronger the reflection ability. For this reason, ultrasonic sensors can be made using this property of ultrasonic waves. In addition, the propagation speed of ultrasonic waves

With the technological advancement of MEMS, laser technology, high-tech materials, etc., the research and development of ultrasonic sensors is showing a diversified trend. Some application biological materials are to simulate human skin and innovate on the tactile sense of ultrasonic sensors; some M

After testing, the gasoline pressure at idling speed is 260Kpa, and it can reach 310Kpa when ultrasonic wind speed measurement is accelerating, indicating that the oil pressure is normal. Read the data stream, the air mass flow rate at idling speed is 2.2g/s, which is lower than the normal value (2~

In the application of ultrasonic weather transducer sensors, the effect of application in the different environments is different. For example, the data displayed on the roof of an empty tall building and on the roof of a low building are different. Let's take a look at some environmental factors th

Principle of UltrasoundLike many ultrasonic sensing applications, UAV landing assistance systems use the time-of-flight (ToF) principle. ToF is an estimate of the round-trip time of the ultrasonic waves emitted from the sensor to the target object and then reflected from the object back to the ultra

Ultrasonic wind transducer is a kind of mechanical oscillation in elastic medium, which has two forms: transverse oscillation (transverse wave) and longitudinal oscillation (longitudinal wave). The application in industry mainly adopts longitudinal oscillation. Ultrasonic waves can propagate in gase
