DETERMINING ROTATIONAL SPEED OR DIRECTION OF A BODY |
| 摘要 |
A device for use in determining the rotational speed of a body. The device includes a sensor for detecting the strength of a magnetic field, and a body that is rotatable relative to the sensor about an axis. The body includes circumferentially spaced magnetic regions. The device is arranged so that, during rotation of the body relative to the sensor, the maximum strength detectable by the sensor of a first magnetic field of a first of the magnetic regions is different to the maximum strength detectable by the sensor of a second magnetic field of a second of the magnetic regions. |

1. A device for use in determining the rotational speed of a body, the device comprising:
a sensor configured to detect a strength of a magnetic field; and a body that is rotatable relative to the sensor about an axis, the body comprising a plurality of circumferentially spaced magnetic regions; wherein the device is arranged so that during rotation of the body relative to the sensor the maximum strength detectable by the sensor of a first magnetic field of a first of the magnetic regions is different to a maximum strength detectable by the sensor of a second magnetic field of a second of the magnetic regions. |
