| 摘要 |
The present invention relates to a device for detecting an explosive substance and, specifically, to an unbalance differential sensor head for detecting an explosive substance comprising: a first transmission coil of a spiral shape, which consists of a first to a sixth substrate forming a hexahedron, and which is equipped on one side of the first substrate; a second transmission coil of a spiral shape, which is equipped on one side of the second substrate arranged to face the first substrate; a first receiving coil of a spiral shape, which is equipped on one side of the first substrate while being equipped around the first transmission coil; and a second receiving coil of a spiral shape, which is equipped on one side of the second substrate while being equipped around the second transmission coil. The first transmission coil and the second transmission coil are connected electrically while facing each other to be in accord with each other inside the hexahedron. The first receiving coil and the second receiving coil are connected electrically while facing each other to be in accord with each other inside the hexahedron. |
