Proximity and strain sensing |
| 摘要 |
There is set forth herein a method comprising applying a drive signal to a drive element in a sensor assembly having a drive element and one or more sensor element so that responsively to the drive signal the drive element generates a magnetic flux that travels through a target, determining a strain of the target using a picked up output signal picked up by the one or more sensor element. In one embodiment, a sensor assembly can be employed for detecting a proximity of the target using a picked up output signal picked up by e.g., the drive element. In one embodiment, a drive signal can have a plurality of frequency components. |

1. A method comprising:
applying a drive signal to a drive element in a sensor assembly having a drive element and one or more sensor element so that responsively to the drive signal the drive element generates a magnetic flux that travels through a target; determining a strain of the target using a picked up output signal picked up by the one or more sensor element; and detecting a proximity of the target using a picked up output signal picked up by the drive element. |
