product description

WT-9HS portable eddy current crack Detector is easy to carry and suitable for online and offline detection of cracks in metal pipes and bars, heat exchange tubes, and short-axis products. It uses an internal penetration probe to detect various defects, corrosion, and wall thickness reduction on the inner wall of the tube. Thin and other abnormalities. It has a relatively independent test channel that can drive a combined probe composed of absolute and differential coils. The detection channel collects data at the same time and is used to detect longitudinal cracks and transverse defects (such as barges) that appear in the production of metal products. It has high sensitivity to axial defects such as bumps and opening cracks. It can reliably detect cracks and damage to products caused by failures during the production process. The signals acquired by the detection channel can be displayed on the screen in real time as impedance plane diagram and time base scan diagram. It can adapt to the testing requirements of various metal products, and due to its fully digital design, it can establish multiple standard testing programs or professional systems in the instrument, which is convenient for users to call when changing product specifications. It is equipped with input and output controls. The interface facilitates the connection between the inspection site and various equipment and works synchronously to form a highly automated whole.

Principle

Eddy Current Testing (Eddy Current Testing) is one of many non-destructive testing (NDT) methods that applies the basic theory of "electromagnetism" as the basis for conductor testing.

Eddy current testing is to bring a conductor close to a probe that is powered by alternating current to establish an alternating magnetic field. The alternating magnetic field passes through the conductor and generates electromagnetic induction with it, creating eddy currents in the conductor. The eddy current in the probe conductor will also produce its own magnetic field. The effect of the eddy current magnetic field will also change the strength of the original magnetic field, which will lead to changes in Voltage and impedance. Therefore, when defects appear in the conductor or the measured metal material changes, the intensity and distribution of the eddy current will be affected. The change in the eddy current will in turn cause changes in the Voltage and impedance of the detection coil. Based on this change, the defects in the conductor can be indirectly known. existence and defects of metal materials.
