description PURPOSE:To perform the correct detection of a rotation automatically by separating the main component of the detecting signal obtd. by detecting the part to be detected with a sensor from the unbalancing component. CONSTITUTION:The detection signal detected by a sensor 3 is amplified by a preamplifier circuit 4 and the main component corresponding to the part to be detected and the unbalancing component by an eccentric rotation are separated by the difference in those frequency components by a separating circuit 5. The separated main component is inputted to a count display circuit 6 to display by counting the number of rotations of a rotary shaft and the digital data thereof are outputted to a control signal output circuit 7 as well. The analog voltage and current proportional to the number of revolutions are outputted and an interlocking signal is outputted by detecting the excess and lack in the number of revolutions as well in the circuit 7. The main component and unbalanced component outputted from the circuit 5 are inputted to an unbalance factor detecting circuit 8 and balance point detecting circuit 9. The voltage corresponding to the ratio of these two components is outputted in the circuit 8 and an interlocking signal is outputted as well when the unbalance factor exceeds as well and in the circuit 9 the phase of the two components are displayed by an angle.
