    • A magnetic sensor arrangement (1), having magnetically sensitive sensor elements (7, 8) whose electrical properties are changeable as a function of a magnetic field that a moving, passive transmitter element (11) is able to influence. The magnetic sensor arrangement (1) has two sensor elements (7, 8) in a gradiometer arrangement that are each respectively associated with one of two magnetic regions (4, 5) of a permanent magnet embodied in the form of a gap magnet (2; 20; 23), which regions are spaced apart from each other by a predetermined distance (sa). The regions (4, 5) and the gap magnet (2; 20; 23)—in terms of the for example wedge-shaped embodiment, the dimensions (h, b, t), the gap width (sa), the gap depth (st), and their positions in relation to the sensor elements (7, 8)—are situated so as to minimize the offset of the output signal of the sensor elements (7, 8) in the gradiometer arrangement.
    • 一种磁传感器装置(1),其具有磁敏感传感器元件(7,8),其电性能可随着移动的无源发射器元件(11)能够影响的磁场而变化。 磁传感器装置(1)具有梯度计装置中的两个传感器元件(7,8),每个传感器元件分别与以间隙磁体(2)形式实现的永磁体的两个磁区(4,5)中的一个相关联 ; 20; 23),哪些区域彼此隔开预定距离(sa)。 根据例如楔形实施例的区域(4,5)和间隙磁体(2; 20; 23)的尺寸(h,b,t),间隙宽度(sa),间隙深度 (st),并且它们相对于传感器元件(7,8)的位置设置为使得在梯度计装置中的传感器元件(7,8)的输出信号的偏移最小化。
