Abstract
A proximity electric current sensing device includes a main body, a first and second adjusting components, a first to third sensing units. The main body has a hole for a conducting wire to go through. The first and second adjusting components are disposed on a first and second sides of the main body respectively for adjusting a first and second positions of the conducting wire. The first to third sensing units are disposed on the main body and adjacent to a first to third sides of the conducting wire respectively for sensing a first to third magnetic fluxes of the conducting wire. The processing unit rotates the adjusting components to ensure the third sensing unit is right above the center of the conducting wire according to the first and second magnetic flux, estimates an installation position, and calculates an amount of an electric current according to the third magnetic flux.
