Eddy Current Testing Machine
Eddy Current Testing Machine is an intelligent detection device designed using the principle of dynamic magnetic eddy current to detect information related to defects on the inner wall of pipelines. The principle of dynamic eddy current refers to the disturbance caused by the dynamic eddy current when a permanent magnet is close to the tested component and there is a discontinuous shape change on the tested component. Therefore, sensors can be used to collect changes in the magnetic field around the magnet to determine the shape change on the component. It can detect most types of internal surface defects, such as metal corrosion, deformation, through holes, effectively detect cracks, etc. It can also detect oil theft branch pipes and quickly issue reports.

FAQ
Q: What are the factors affecting accuracy?
A: Material characteristics: Uneven material conductivity and permeability may lead to increased substrate noise (requiring magnetic saturation optimization).
Surface condition: Excessive roughness can interfere with the distribution of eddy current fields. It is recommended to pre treat the surface being tested.
Environmental interference: Temperature fluctuations or electromagnetic interference need to be suppressed through adaptive filtering algorithms.
Q: Daily maintenance suggestions?
A: Regularly calibrate sensor sensitivity to ensure conductivity measurement error ≤ 1%.
Avoid prolonged exposure of the probe to high temperatures or corrosive environments.
Q: Material adaptability?
A: Conductive materials: Copper, aluminum, steel and other metals are suitable, while non-magnetic materials require the combination of other technologies (such as ultrasound).
Coating thickness detection: The eddy current thickness gauge can cover the range of 0-2000 μ m with an error of ± 1 μ m.
Q: Security guarantee?
A: Support explosion-proof certification (Ex d IIB T4), suitable for flammable and explosive environments such as oil and gas, chemical, etc.
Compliant with industrial grade waterproof standards (IP65), suitable for high humidity or dust conditions.
