Mitech Ultrasonic flaw detector MFD550B
Product Overview
Based on ultrasonic principle, digital ultrasonic flaw detector
MFD550B can test, orient, evaluate and diagnose various flaws such
as crack, lard, air hole in workpiece’s interior swiftly and
accurately without any destruction. With full digital 640X480 TFT
LCD display, it show the defect clearly under the dim light and
strong sunlight environment. 0-9999mm measuring range 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 ion battery module,it can work more
than 10 hours continuously. Full English master-slave menu,
emphasizing on user experience, collecting shortcut keys, digital
shuttle rotary wheel, cross menu three operating ways inone body,
customers with different habits can operate it freely. With
comprehensive performance self-checking function, it can
automatically generate test reports and support for many languages.
With high cost performance, it is the smart choice for the
practical economic model of ultrasonic testingequipment.
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.
