Hello,everyone.
This is our far-field eddy current flaw detector, the distance between the excitation coil and the detection coil is 2-3 times the inner diameter of the detection pipe fitting, which is called the far field. The track of the magnetic field line in the far field region is parallel to the pipe wall, so the total number of magnetic field lines passing through the material wall in the far field region is proportional to the wall thickness. Compared with conventional eddy current, magnetic flux leakage and ultrasonic nondestructive testing, far field eddy current nondestructive testing has the following advantages: the surface of the tested material does not need to be cleaned; The probe is not in contact with the surface of the material, and the change of the gap between the outer diameter of the probe and the inner diameter of the material has little influence on the detection result. The sensitivity of detecting the corrosion pit on the inner surface and the outer surface of the material is the same. It has very high sensitivity for the detection of uniform thinning, gradual thinning and off-wear thinning. Whether the detection speed of the probe is uniform has no effect on the detection result. The gas and liquid medium in the material have no influence on the detection results. The testing equipment is small in size and light in weight, which is convenient for flexible application in the field. The detection data can also be stored for long-distance detection
