WebElectronic coating thickness instruments can be used to measure coating thickness on metallic substrates. Commonly used techniques are electromagnetic induction and eddy currents. Electromagnetic induction is used for magnetic substrates such as ferrous materials, whilst the eddy current method is employed when the substrate is non-ferrous. WebOct 8, 2024 · Eddy currents are used in specific applications including non-destructive testing. As mentioned, eddy currents are electric fields that are generated by a magnetic field, but the strength of an eddy current field is proportional to the strength of the magnetic field, as well as the area of the field and the change in flux. ...

WebEddy current testing is typically used for nonconductive coatings, and ultrasonic for most standard wall thickness testing measurements. In many large-scale manufacturing efforts, using the right equipment for the job is the only way to succeed. When it comes to ultrasound or eddy current testing for thickness measurement, the same is true. WebThe frequency used to drive the eddy current probe is 50 kHz. First, since relative permeability is given, it must be converted to an absolute permeability value. Given the equation and the permeability of free space (u 0 ) of 1.257x10 -6 H/m Rearranging this equation to solve for absolute permeability results in: μ r = μ μ 0 \mu_{r}=\frac ... hon. cynthia wright senior judge
