Product Overview
based on ultrasonic principle, digital ultrasonic flaw detector MFD350B with 320*240 TFT LCD, it can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. It can be used in Laboratory as well as in engineering filed. With range of 0-6000mm, it can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium battery module, it can be long standby for months. High quality with low price, it is the first choice for the practical economic model for ultrasonic testing equipment.
Working Principle
When presence of a defect in a workpiece with homogenous material, due to the defects, it will inform the interface among different mediums between the defect and workpiece. As the acoustic resistance is different at the interface, after the pulsing ultrasonic wave met the interface, it will produce reflection. The reflected energy will be received by the probe. Then it will show a reflection waveform in a certain abscissa position in the display screen which is the defect depth in the workpiece. The height and shape of reflecting wave would be different caused by the different defects which reflect the defect’s character.
