DEVICE FOR MEASUREMENT OF ANGLE OF SLANTED SURFACE Russian patent published in 2015 - IPC G01B11/26 

FIELD: measurement equipment.

SUBSTANCE: device comprises axle-mounted flange and dial, two reading channels, device for digital processing and averaging of results from reading channels, digital indicator. The reading channels contain respectively LEDs, condensers, verniers, photodetectors and interpolators. The dial has a circular transparent zone, circular measuring scale and zero mark scale. The verniers have transparent zones and scales. During rotation of the dial the photodetectors generate the signals SIN (α×N) and COS (α×N), where α - current angle of dial rotation; N - total of scale marks of the dial measuring scale. The interpolators generate two sequences of rectangular pulses shifted with reference to each other by quarter of their period in one or another side. The device for digital processing and averaging of results from reading channels averages the data with indicating by the digital indicator.

EFFECT: improvement of accuracy and recurrence of results of measurements, improvement of convenience of operation, minimising of time for measurements, possibility of automatic measurement of difference of angles of slant of two planes.
