DEVICE TO CHECK SPEED OF ROTATION OF WORKING MEMBERS OF AGRICULTURAL MACHINES Russian patent published in 1996 - IPC

Abstract RU 2067378 C1

FIELD: agricultural engineering. SUBSTANCE: rotation speed pickup forms pulses by signal reflected from strip whose frequency corresponds to speed of shaft rotation. Signal of pickup is converted in control unit and multiplier and is compared with signal from standard frequency pulse generator. Speed of shaft rotation is evaluated basing on comparison of results. Data are displaced. EFFECT: enhanced reliability of checking. 5 cl, 2 dwg
