Summary: | To suppress decrease in sensitivity of a metal detector.SOLUTION: In a metal detector 1 having at least one transmitter coil 7 and at least one receiver coil 8, the transmitter coil and the receiver coil are arranged in a housing 6. The transmitter coil and the receiver coil are wound around a bobbin, and the bobbin forms a search channel 4. A conveyance device 2 conveys a product through the search channel. The bobbin has an external surface oriented in a direction of an inner space of the housing, and a search channel surface oriented in a direction of the conveyance device 2. The transmitter coil and the receiver coil are arranged on the external surface of the bobbin and connected to a measuring device. In the metal detector, the bobbin is formed of a support material, an electrically conductive layer is disposed on the search channel surface of the bobbin, and the electrically conductive layer is interrupted by at least one groove.SELECTED DRAWING: Figure 1
【課題】金属検出器の感度の低減を抑制する。【解決手段】少なくとも1つの送信コイル7及び少なくとも1つの受信コイル8を有する金属検出器1であって、送信コイル及び受信コイルは、ハウジング6内に配置されており、送信コイル及び受信コイルは、巻枠に巻回されており、巻枠は、探索チャネル4を形成し、搬送装置2は、探索チャネルを通るように製品を搬送し、巻枠は、ハウジングの内部空間の方向に配向されている外面と、搬送装置2の方向に配向されている探索チャネル面と、を有し、送信コイル及び受信コイルは、巻枠の外面に配置されており、且つ測定装置に接続されている、金属検出器において、巻枠は、支持材料から成り、巻枠の探索チャネル面には、導電層が配置されており、導電層は、少なくとも1つの溝によって中断されている。【選択図】図1 |
