<p><P>PROBLEM TO BE SOLVED: To provide a load capacity sensor which senses the load capacity of a wiring duct, in which conductors are housed, easily and accurately. <P>SOLUTION: The load capacity sensor 3 senses the load capacity of the wiring duct 1 in which positive and negative parallel conductors are arranged in a case of which one side is provided with an opening. The sensor comprises a voltage detection means comprising two coils 33 in series which are inserted from the opening to the inside of the case, are arranged at the nearly center between the parallel conductors 22, and generates opposite phase induced voltages by magnetic flux generated by the flow of electric current through the parallel conductors 22 and a wiring duct fixing part 32 which detachably fixes the voltage detection means to the rim of the opening. The load capacity of the wiring duct 1 determined in accordance with a voltage detected by the voltage detection means is outputted to a display means which displays the load capacity. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
