Amperometry method and amperometry device

摘要

Guarantee of electric insulation is easy although and also, it is possible, furthermore heat generation it prevents reliability improves to assure the miniaturization of the electric current sensor, ideal amperometry method is offered. The printed circuit board it has with the electric current sensor 100 of the non contact type which is mounted on 3 which possesses suffering measurement conductor 4 and the printed circuit board 3 aspect, it mounts electric current sensor 100, on the surface 92 of opposite side to the surface where the inside suffering measurement conductor 4 of the surface of printed circuit board 3 is provided. Because of this, because electric current sensor 100 is mounted on back 92, comparing until recently, it is possible to guarantee electric insulation relatively easily with the downstream conductor and suffering measurement conductor 4 of electric current sensor 100.
