Portable ultrasonic flaw detector is a non-destructive flaw detection instrument. It can detect several kinds of defects in the workpiece quickly, without damage, and accurately. Ultrasonic flaw detectors are sound waves that have a frequency higher than 20kHz, exceed people's ear discrimination technology, and are very penetrating.

There are many applications of portable ultrasonic flaw detectors, such as measuring distance with ultrasonic reflection, and using high-power ultrasonic vibration to remove scale attached to the boiler.

Portable ultrasonic flaw detectors now usually emit ultrasound to the tested object (such as industrial materials, human body), and then use its reflection, Doppler effect, transmission, etc. to obtain the information inside the tested object and process it to form an image.

Portable ultrasonic flaw detector, the Doppler effect method is to use the Doppler frequency shift effect that occurs when ultrasound encounters a moving object to obtain the characteristics of the movement direction and speed of the object; the transmission law is to analyze the ultrasonic penetration The internal characteristics of the object are obtained by measuring the changes after the object, and its application is still in the development stage.
