    • A position sensor (10) is disclosed having a transducer (14) formed by a Hall-effect device (24) and permanent magnet (22) secured within a housing (20) on either side of a low permeability gap (26). A target (12) secured to an active member (16), such as an EGR valve plunger moves within the gap (26). The target (12) has a flux modulating property that varies with position along a direction of travel (18). Variable reluctance is achieved in some embodiments by varying the cross section of the target (12) with position. In some embodiments, a second target (12b) having substantially constant reluctance secures to the active member (16) and moves within a gap (26) defined by a second transducer. The output of the second transducer (14b) is used to normalize the output of the first transducer (14a) and compensate for anomalies such as drift and movement other than in the direction of travel (18) of the active member (16).
    • 公开了一种位置传感器(10),其具有由霍尔效应装置(24)和永磁体(22)形成的换能器(14),永久磁铁(22)固定在低渗透间隙(26)的任一侧上的壳体(20)内。 固定到诸如EGR阀柱塞的活动构件(16)上的目标(12)在间隙(26)内移动。 目标(12)具有随着行进方向(18)的位置而变化的磁通调制特性。 在一些实施例中,通过用位置改变目标(12)的横截面来实现可变磁阻。 在一些实施例中,具有基本上恒定的磁阻的第二目标(12b)固定到有源构件(16)并且在由第二换能器限定的间隙(26)内移动。 第二换能器(14b)的输出用于对第一换能器(14a)的输出进行归一化,并且补偿除活动构件(16)的行进方向(18)之外的异常,例如漂移和运动。
