A transducer (probe) is a device that converts physical energy into and out. An ultrasonic probe converts electrical energy into acoustic energy and converts acoustic energy into electrical energy. The energy conversion is realized. Therefore, the ultrasonic probe is also called an ultrasonic transd

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

In the industrial production, various sealed liquids are often used to store high-temperature, toxic, volatile, flammable, explosive, and highly corrosive liquid media. For ultrasonic depth transducer of these containers, non-contact measurement must be used.When the ultrasonic level gauge is used f

A pulse (emission wave) generated by the high-frequency pulse generator is applied to the ultrasonic sensor probe to excite the piezoelectric crystal to oscillate to generate ultrasonic waves. Ultrasonic waves propagate to the inside of the workpiece at a certain speed. A part of the ultrasonic wave

Ultrasound refers to mechanical waves with a frequency higher than 20 kHz. In order to use ultrasonic waves as a detecting means, it is necessary to generate ultrasonic waves and receiving ultrasonic waves. The device that performs this function is an ultrasonic sensor, which is customarily called a

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

The core of the underwater acoustic transducer is a piezoelectric wafer in its outer casing, and there are many kinds of materials constituting the wafer. The size of the wafer, such as diameter and thickness, varies, so the performance of each probe is different and its performance must be known be
