Mitech MFD500B Ultrasonic Flaw Detector:

Product Overview

Based on the ultrasonic theory, the digital ultrasonic flaw detector Mitech MFD500B with 320*240 TFT LCD can quickly and reliably test, orient, assess, and diagnose a variety of faults such cracks, grease, and air holes in the interior of a workpiece without causing any damage.Both laboratories and the engineering field can use Mitech MFD500B Ultrasonic Flaw Detector.

Working Principle

When a flaw appears in a workpiece made of homogeneous material, the defect will reveal the interface between the defect and the workpiece’s other media. The pulsating ultrasonic wave will create reflection when it comes into contact with the interface because the acoustic resistance is different there.The probe will take in the energy that has been reflected. The fault depth in the workpiece will then be represented by a reflection waveform at a specific abscissa point on the display screen.

Due to various imperfections, each of which reflects the nature of the defect, the height and form of the reflecting wave will change.
