BKN eddy current testing machines provide non-destructive inspection for tubes, bars, and wires, detecting surface defects, cracks, and material inconsistencies while supporting high-speed production, automation, customization, and reliable industrial quality control.
Eddy current testing equipment uses electromagnetic induction to inspect conductive metals without damaging the workpiece. BKN's eddy current NDT equipment is designed for detecting surface and near-surface defects in tubes, bars, wires and automotive components, with solutions for automated production-line inspection and material sorting.
The principle of eddy current ndt equipment is that the coil with alternating current is placed on the metal plate to be measured or outside the metal, tube to be measured (see figure). The alternating magnetic field will be generated inside and near the coil, which makes the induced alternating current in the sample appear to be eddy, which is called eddy current. Under certain conditions, the current through the coil is invariable. If the coil is close to the workpiece under test, like a ship in the water, the eddy current will be induced in the workpiece. Under the influence of the eddy current, the coil current will change. When the probe coil approaches the workpiece, eddy currents are induced in the conductive material. Defects or changes in material properties alter the eddy current response and coil impedance. Eddy current inspection equipment analyzes these signal changes to identify cracks, surface defects and other material discontinuities without damaging the workpiece.
Eddy current testing is a non-contact testing method, which mainly uses electromagnetic field and electromagnetic induction between metals to detect.
