【実用新案登録請求の範囲】[Scope of utility model registration request] 棒状永久磁石の一端面にヨークの一端を接合し、ヨーク
周面にコイルを巻装して成る電磁誘導式検出器において
、ヨークの形状を先端側が小径のテーパ状にしてヨーク
中の磁束密度を最適動作点の磁束密度と略一致せしめる
ことを特徴とする電磁誘導式検出器。In an electromagnetic induction detector in which one end of a yoke is bonded to one end of a rod-shaped permanent magnet and a coil is wound around the yoke, the shape of the yoke is tapered with a small diameter on the tip side to reduce the magnetic flux density in the yoke. An electromagnetic induction detector characterized by making the magnetic flux density substantially match the optimum operating point.
