传感器组件
摘要：
一种传感器组件(118)包括外壳、屏蔽构件(156)、磁场传感器(158)和感测磁体(126)。所述外壳配置为至少安装在电磁线圈附近，所述电磁线圈产生第一磁场，以基于所述第一磁场的强度，使得可移动部件沿着轴线线性地移动。所述感测磁体(126)配置为联接到所述可移动部件以与其一起移动。所述磁场传感器(158)和所述感测磁体(126)设置在由所述屏蔽构件(156)限定的屏蔽室内，所述屏蔽构件为铁质的，以将所述磁场传感器和所述感测磁体与所述第一磁场屏蔽。所述磁场传感器检测响应于由所述感测磁体产生的第二磁场的电特性，以监测所述可移动部件沿着所述轴线的位置。
摘要（英）：

A sensor assembly includes a housing, a shield member, a magnetic field sensor, and a sensing magnet. The housing is configured to be mounted at least proximate to an electromagnetic coil that generates a first magnetic field to cause a movable component to move linearly along an axis based on the strength of the first magnetic field. The sensing magnet is configured to be coupled to the movable component to move therewith. The magnetic field sensor and the sensing magnet are disposed within a shielded chamber defined by the shield member, which is ferrous to shield the magnetic field sensor and sensing magnet from the first magnetic field. The magnetic field sensor detects an electrical characteristic responsive to a second magnetic field produced by the sensing magnet to monitor a position of the movable component along the axis.
