METHOD AND DEVICE FOR MEASURING ANGLE OF TILT Russian patent published in 2018 - IPC G01C9/06 G01C9/24 

FIELD: electronics.

SUBSTANCE: invention can be used in systems of visual and electronic remote determination of the spatial position of objects relative to the horizon using bubble-type levels. Above method’s essence consists in the following: simultaneously with the visual measurement of the displacement of the gas bubble freely floating in the liquid along the concave surface of the meniscus, photocurrents from the light spot of the bubble and polarization currents from its spatial position in the cavity are measured, and then compared with each other. For this purpose, film photoresistors are introduced into the device, the former are executed in the form of four congruent circular quadrants, as well as optically transparent film electrodes, made in the form of four congruent spherical triangles in such a way, that their projections onto the base coincide with the circular quadrants of film photoresistors and form the plates of four capacitors. Wherein two opposing film electrodes and two opposing film photoresistors, whose bisectors of the central angles are collinear with one of the orthogonal coordinate axes, are electrically connected to each other and a power source in the measuring bridge, whose measuring diagonal is electrically connected to the corresponding channel of the indicator.

EFFECT: technical result consists in creating a small-sized sensor with small angles of inclination with visual measurement and simultaneous conversion of the direction and magnitude of the inclination into an electrical signal; as well as in increasing the measurement accuracy and expanding the dynamic range of the measured quantities.
