Claims

[Scope of utility model registration request]

The axis A passing through the center of the hollow annular moving coil is horizontal,
In a position where plane B passing through approximately the center of the width of the orthogonal coil is vertical, a movable coil to which a light-shielding piece for adjusting the photocurrent of the photoelectric element is fixed is suspended vertically from above and below with a tension band, and the outside of the tension band is suspended vertically from above and below. The movable part is supported by fixing the end to a tension spring, and all supporting points of the tension band are in plane B, so that the movable part is in equilibrium with gravity, and this moving coil is placed in a radial magnetic field. It can be placed within the space of. When surface B is tilted from this vertical state, the movable part is sagged and displaced in the direction of axis A due to gravity, but at this time, the relative position between the light shielding piece and the photoelectric element is shifted, and the photocurrent changes.
The bridge that was maintaining balance becomes unbalanced, and current flows through the moving coil, and the electromagnetic action of this current generates a force in the opposite direction to gravity, which tries to push the moving part back, and stops at a position where both forces are balanced. A tension-type moving coil type instrument with a structure that detects the angle of inclination.
