Patent ID: 8836318

Claim:
A proximity electric current sensing device, comprising: a main body having a hole for a conducting wire to go through the main body; a first adjusting component disposed on a first side of the main body for adjusting a first position of the conducting wire; a second adjusting component disposed on a second side of the main body for adjusting a second position of the conducting wire; a first sensing unit disposed on the main body and adjacent to a first side of the conducting wire for sensing a first magnetic flux of the conducting wire; a second sensing unit disposed on the main body and adjacent to a second side of the conducting wire for sensing a second magnetic flux of the conducting wire; a third sensing unit disposed on the main body and adjacent to a third side of the conducting wire for sensing a third magnetic flux of the conducting wire; a processing unit coupled to the first sensing unit, the second sensing unit and the third sensing unit being configured to determine a position of the conducting wire according to the first magnetic flux and the second magnetic flux, and to calculate an amount of an electric current according to the third magnetic flux; a third adjusting component disposed on a third side of the main body for adjusting a third position of the conducting wire; a fourth adjusting component disposed on a fourth side of the main body for adjusting a fourth position of the conducting wire; and a fourth sensing unit disposed on the main body and adjacent to a fourth side of the conducting wire for sensing a fourth magnetic flux of the conducting wire; wherein the processing unit is further coupled to the fourth sensing unit for determining another position of the conducting wire according to the third magnetic flux and fourth magnetic flux.
