PURPOSE:To enlarge the turning torque of a movable magnet by applying an inverting output of a sine wave (cosine wave) voltage applied to one terminal of a cross coil to the other terminal and making the potential difference between both terminals of the coil large. CONSTITUTION:Using a sine wave and a cosine wave as a signal source in this gauge, the outputs of amplifiers 7, 8 are applied to one terminals 2b, 3b of two cross coils 2, 3 when A times amplifiers 7, 8 are used. Each signal source is inverted around a predetermined voltage, and applied to the other terminals 2a, 2a of the coils 2, 3 by inverting -A times amplifiers 5, 6. Therefore, the potential difference between two terminals of the coil becomes large, so that the turning torque of the movable magnet can be enlarged. |
