Since the introduction of the 2D rebar detector, there have been small friends asking what is the 2D rebar detector. I do n’t understand what the 2D rebar detector means and what are the advantages. Today I’ll make you a detailed answer.

The two-dimensional of the two-dimensional rebar detector means that the steel bar instrument can detect two dimensions at the same time, that is, the magnetic field in two directions, which is different from the one-dimensional rebar detector can only detect the magnetic field in one direction, and its detection ability is improved compared to the one-dimensional rebar detector.  Its advantages are mainly reflected in the following two points.

One: unique anti-interference ability

The first is the unique anti-interference ability of the two-dimensional rebar detector.

First look at the professional interpretation of the R & D engineer: the composite sensor of the 2D rebar detector adopts a multi-array arrangement structure, which can simultaneously detect the magnetic field induction signals (such as board / wall components) generated by the metal substances in the two vertical directions of X and Y The transverse and longitudinal reinforcement; or the main reinforcement and stirrup of beam / column members), through our signal processing technology and the corresponding algorithm independently developed, we can get the influence of the interference (the magnetic field of the reinforcing steel in the other direction) and remove it. It produces a more realistic signal of the tested steel bar. Therefore, the accuracy and stability of its dense dense meshes are greatly improved.

Editor's Interpretation: Because the two-dimensional rebar instrument can distinguish the magnetic interference of the main and stirrups and automatically correct it, the accuracy of testing the protective layer of dense steel mesh is much better than that of the one-dimensional rebar detector.

Two: CT imaging function

Professional interpretation of R & D engineers: Two-dimensional composite sensors can recognize magnetic fields in both horizontal and vertical dimensions. The sensors are arranged in a two-dimensional matrix, which can be regarded as the effect of sensor clusters. After each scanning point is processed, a relatively pure magnetic field signal can be obtained (removing the interference of the magnetic field of the steel bar in the other direction, and the signal of the steel bar in the measured direction is retained). The magnetic field signals scanned at each point are aggregated together to form the distribution of the steel bar through the algorithm image. Therefore, after scanning the surface of the component according to the configuration drawing, the two-dimensional steel detector can present the CT image of the steel plane inside the component. Diagonal ribs, cross ribs, and irregularly arranged ribs can all be easily solved for one-dimensional steel bar headaches.
