ABSTRACT:
In a crossed-coil rotating-magnet measuring instrument having an approximately cylindrical core developed as winding form, a first and second coil are wound crossed one above the other. The second coil is necessarily arranged over the first coil in the regin of the ends of the winding form and thus has a greater height of winding than the latter. Within the core there is also provided a rotating magnet whose pointer shaft is extended out of an extension of the core. In order to reduce the linearity error of this measuring instrument and to permit a reading over several quadrants, spacer means are provided on the core for guiding turns of the coil spaced from the extension of the core around the latter in a rectangular plane in each case. In combination with this, the core is developed with a large diameter in the winding region of the first coil, said diameter being of such a value with respect to the diameter of the winding region of the second coil that the average lengths of the turns of the two coils are the same.
