  • Patent number: 4827210
    Abstract: In a cross-coil moving-magnet measuring instrument having an approximately cylindrical core developed as winding form, a first coil and a second coil are wound crosswise one over the other. The second coil is necessarily arranged over the first coil in the region of the ends of the winding form and thus has a greater height of turn than the latter. Within the core there is furthermore mounted a moving magnet whose pointer shaft is brought out from an extension of the core. In order to reduce the errors in linearity of this measuring instrument and to permit a display over several quadrants, spacing elements are arranged on the core, they serving to guide turns of the coil, spaced from the extension of an core, around the latter in planes which are at right angles to each other.

  • Patent number: 4633174
    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.

  • Patent number: 4567434
    Abstract: In an analog display device, a pointer (1) can be reset by a stepping motor (2) which receives a constant number of pulses upon a reset command. In this way, starting from any position, the pointer is certain to reach the stop which corresponds to its zero position. In order in this connection to keep the mechanical force on the stop (6) and the transmission elements (3 and 4) between the pointer and the stepping motor small, the pulses for the resetting are produced initially with a relatively low pulse frequency and then with a higher pulse frequency. As a result, the stepping motor starts up reliably with a relatively high driving torque but gives off only a smaller driving torque when the stop in the zero position is reached.
