  • Sensor having mutually perpendicular sections using zigzag coils for detecting displacement
    Patent number: 5381091
    Abstract: A sensor having a wide sensing range is capable of being controll by a small scale processor. The sensor comprises: a plurality of planar zigzag coils being provided on substrates, the planar zigzag coils having the same coil pitch and being formed into zigzag shape in a first direction, the planar zigzag coils being capable of relative movement in the first direction, the planar zigzag coils including a first planar zigzag coil, which is a primary coil, and a second planar zigzag coil, which is a secondary coil; a magnetizing unit for magnetizing the first planar zigzag coil; a first detecting unit for detecting induced electromotive force, which is induced in the second planar zigzag coil by the first magnetized planar zigzag coil; and a second detecting unit for detecting displacement length between the first planar zigzag coil and the second planar zigzag coil on the basis of the induced electromotive force in the second planar zigzag coil.
