UNBALANCE METER Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: unbalance meter has two vibration sensors 1 and 2, buffer amplifier and integrators 5 and 6, analog-to-digital converter 19 and reading register 21 connected in series. Computer 25, timer 26, permanent storages 28 and 29, on-line storage 30 and unit 31 of control and display are connected in parallel to three wires 24, 23, 22 of control, data and address. Mark sensor 32 is coupled via amplifier 33 directly to computer 25. Clock generator 34 generates clock frequency to computer 25 and timer 26. Computer controls tunable filter 8 and amplifier 14 via control register 27. Meter determines value and angle of unbalance, rotational speed, performs harmonic and spectral analysis of vibration signal, records information in on-line storage, calculates influence coefficients of balancing and correcting masses with single- and multiplane balancing. EFFECT: improved efficiency in determination of unbalance, in measurement and analysis of vibration, in recording and storage of vibration information. 3 cl, 1 dwg
