FIELD: measurement technology. SUBSTANCE: proposed process and gear are based on measurement of signals U1 and U2 of two identical position pickups with bell-shaped transfer characteristic mounted along path of travel and on determination of coordinate function to compute speed. Gear has two controlled keys, adder, subtracter, threshold element, divider, differentiator, two nonlinearity units and multipliers. EFFECT: raised accuracy of measurement of speed of object. 2 cl, 2 dwg
