换能器由一个三腿铁磁芯（2; 6）的至少一个腹板中，中间臂（6）（8; 6A; 7; 6B; 9），并通过电导体（1）至少部分是U形的环绕是 ， 每个腹板（8; 6A; 7; 6B; 9）具有至少三个空气间隙（7，8，9），其所有，但两个外气隙的（8,9）的至少一个，在所示的例子中，三个磁场传感器（3，3A ，3b）中，其中，对于实施例中，通过并排布置在平行的侧。 中间腿（6）和所述磁场传感器（3，3A，3B）一起形成一个结构单元。 在每个幅材，所述两个外空气间隙（8,9），在中央分支的纵向方向上测得的（6）比相同的web的所有其他Sumpe气隙（7）的长度更长。 总共有总是至少两个磁场传感器（3，3A，3B）中存在的中间臂（6）。 该换能器特别适用于在多功能仪器节约成本的安装。

The transducer consists of a three-leg ferromagnetic core (2; 6), the central limb (6) of at least one web (8; 6; 7; 6b; 9) and at least partially by an electrical conductor (1) U-shaped surrounded , Each web (8; 6a; 7; 6b; 9) has at least three air gaps (7, 8, 9), of which all but the two outer air gaps (8, 9) at least one, in the example illustrated three magnetic field sensors (3, 3a , 3b), which, for. example, are arranged parallel side by side. The center leg (6) and the magnetic field sensors (3, 3a, 3b) together form a structural unit. In each web, each of the two outer air gaps (8, 9), measured in the longitudinal direction of the central limb (6) is longer than the lengths of all other Sumpe the air gaps (7) of the same web. There are always at least two total magnetic field sensors (3, 3a, 3b) available at the central limb (6). The transducer is particularly well suited for cost-saving installation in multifunctional instruments.
