metalelektro eddy current flaw detector operating principle

The operating principle of the metalelektro eddy current flaw detector is to measure the magnetic field induced by eddy currents. It is suitable for detecting structural defects and manipulation in the upper layers of conductive materials, metal sheets, and vehicle bodies. The instrument is calibrated for steel and aluminum bodywork widely used in automotive manufacturing.

Instruments using eddy current measurement technology can simultaneously separate and measure changes in base metal mass and coating thickness. Thanks to the microprocessor-supported measurement process, a high-sensitivity intelligent device has been designed, enabling easy and rapid inspection.

The device's design and small size allow for non-destructive, rapid measurements in hard-to-reach areas. Due to the measurement principle, variations in surface irregularities (or coating thickness) and measurement angle do not cause measurement errors during material quality assessment. Welds, joints, and cracks can be detected even under 2 mm coatings.

During inspection of vehicle chassis numbers, changes in material continuity (such as chassis numbers or implanted bearing components) and manipulations involving significant heat input (forgeries) can be accurately displayed. During the inspection process, the instrument's two measurement functions complement each other well, as forgery methods that alter material structure typically also result in changes to the coating layer.

Built-in Bluetooth functionality enables online data acquisition during measurement.

However, if an online connection is unavailable, the device can also be used as a handheld unit.

Measurement results can be stored and evaluated via software. The software automatically evaluates changes in material structure detected by the measurement based on initial calibration.
