Ultrasonic testing technology is a typical non-contact measuring method, which is based on electronics, materials science, physics, etc., and it is widely used. As a type of wave, ultrasonic transducers have all the properties of a wave. Ultrasonic testing is achieved by the physical process of ultr

One can hear that the sound is generated by the vibration of the object. Its frequency of transducer for distance is in the range of 20HZ-20KHZ, the ultrasonic wave is more than 20KHZ, and the infrasound wave is lower than 20HZ. Commonly used ultrasonic frequencies are tens of KHZ-tens of MHZ. Since

Types of Ultrasonic distance measuring sensorUltrasound has the advantages of strong directivity,which slows energy consumption and long distance of propagation. Therefore, in the transducer for distance by using sensor technology and automatic control technology, ultrasonic ranging is the most popu

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

In the industry, the typical application of ultrasonic distance transducers are non-destructive testing of metals and ultrasonic thickness measurement. In the past, many technologies were hindered by inability detecting the inside of objects, and the emergence of ultrasonic sensing technology change

The ultrasonic transducers is bonded with two symmetrical metal shells and piezoelectric ceramic discs are polarized in the thickness direction with super glue to form a metal-ceramic composite type, its working mechanism is transforming for the high-impedance,small-radial expansion and contraction

A device for transmitting and receiving ultrasonic waves, which is called an ultrasonic transducer or ultrasonic probe; an ultrasonic transducer and transceiver circuit constitutes an ultrasonic sensor. In order to develop a large-range ultrasonic sensor, it is necessary to understand the physical p
