How is wire thickness measured
Webρ is the resistivity; d is the thickness of the material. Four measuring probes with the same spacing are placed in a row on the surface, with a known current flowing between the two outer ones and the potential difference, i.e. the electrical voltage between these probes, being measured using the two inner probes. WebThe thickness of coatings can be measured non-destructively using the magnetic induction method. The prerequisite for this is a magnetizable base material, for example steel or iron. The coating, on the other hand, must be non-magnetic. This process is therefore suitable for measuring galvanic coatings such as zinc and chrome, as well as …
