差動型検出器。It consists of a primary excitation coil wound around a core, and multiple secondary coils wound differentially on both sides of this coil or on top of the primary coil. In a detector that non-contactly detects the gap between the two due to the unbalance of magnetic flux when the magnetic flux is unbalanced, a cylindrical body with multiple single-turn coil-shaped conductors with parts missing is attached to the outside of the coil. A single-turn coil is formed by short-circuiting the conductor, and the output voltage of the differentially wound secondary coil is adjusted to be smaller at an infinite detection distance than at other detection distances. Non-contact differential type detector.
