Electromagnetic induction method exploration
Convert the change in impedance to the distance between the probe and the magnetic material! It measures the position of rebar and the cover thickness.
The electromagnetic induction method for rebar detection generates a magnetic flux by passing an alternating current through an excitation coil wound in a circular shape with copper wire inside the probe. When a magnetic material such as rebar is present within the generated magnetic flux of the excitation coil, a current flows through the magnetic material, creating a magnetic flux in the material as well. As the distance between the probe and the magnetic material changes, the magnetic flux of the material also changes, causing a current to flow in the detection coil within the probe, which results in a change in the voltage of the detection coil. This change in impedance is converted into the distance between the probe and the magnetic material, allowing for the measurement of the position and cover thickness of the rebar. 【Conditions for Accurate Measurement of Rebar Situations】 ■ One rebar nearby ■ One rebar within a wide pitch in the magnetic flux ■ One rebar within the range of the magnetic flux *For more details, please refer to the related link page or feel free to contact us.
