SYSTEM AND METHOD OF MAGNETIC SHIELDING FOR SENSORS |
| 摘要 |
A system includes a magnetostrictive sensor. The magnetostrictive sensor includes a driving coil configured to receive a first driving current and to emit a first magnetic flux portion through a target and a second magnetic flux portion. The magnetostrictive sensor also includes a first sensing coil configured to receive the first magnetic flux portion and to transmit a signal based at least in part on the received first magnetic flux portion. The received first magnetic flux portion is based at least in part on a force on the target. The magnetostrictive sensor further includes a magnetic shield disposed between the driving coil and the first sensing coil. The magnetic shield is configured to reduce the second magnetic flux portion received by the first sensing coil. |

1. A system comprising:
a magnetostrictive sensor comprising:
a driving coil configured to receive a first driving current and to emit a first magnetic flux portion through a target and a second magnetic flux portion;a first sensing coil configured to receive the first magnetic flux portion and to transmit a signal based at least in part on the received first magnetic flux portion, wherein the received first magnetic flux portion is based at least in part on a force on the target; anda magnetic shield disposed between the driving coil and the first sensing coil, wherein the magnetic shield is configured to reduce the second magnetic flux portion received by the first sensing coil. |
