DISPLACEMENT SENSOR |
| 摘要 |
A displacement sensor includes: an first yoke that is formed of a soft magnetic body and is annular-shaped; an second yoke that is formed of a soft magnetic body and is annular-shaped, the second yoke having an inner circumferential surface which faces an outer circumferential surface of the first yoke via a gap and arranged coaxially with the first yoke; a magnet that is arranged to be capable of moving in an axial direction in a radial-direction central portion of the first yoke and is magnetized in the axial direction of the first yoke; and a detection element that detects a magnetic flux density which is generated in the gap and is arranged in the gap so that the magnetic flux density is detected along the radial direction of the first yoke. |

1. A displacement sensor comprising:
an first yoke that is formed of a soft magnetic body and is annular-shaped; an second yoke that is formed of a soft magnetic body and is annular-shaped, the second yoke having an inner circumferential surface which faces an outer circumferential surface of the first yoke via a gap and arranged coaxially with the first yoke; a magnet that is arranged to be capable of moving in an axial direction in a radial-direction central portion of the first yoke and is magnetized in the axial direction of the first yoke; and a detection element that detects a magnetic flux density which is generated in the gap and is arranged in the gap so that the magnetic flux density is detected along the radial direction of the first yoke. |
