Abstract
PURPOSE: To eliminate the error in the partial pulse interval of r.p.m. testing pulses so as to accomplish the highly accurate metering operation by holding for a preset time the outputs of a rotational irregularity meter and an F-V converter in respnose to two delay holding signals for each pulse which is generated for each rotation of a rotor.
CONSTITUTION: The r.p.m. detecting pulses, which are generated by a striped tape 3 and an optical sensor 4 in accordance with the rotations of a rotor 1, are introduced into a rotational irregularity meter 8. A mark 6 is formed at a point of the cirmumference of the rotor 1, and one pulse generated by one rotation of the rotor 1 is generated by an optical sensor 7 and is fed to the rotational irregularity meter 8. More specifically, the one pulse for one rotation from the sensor 7 is fed to a delay circuit 81, which is mounted in the meter 8, and further to a hold designating circuit 82 a preset time after so that the output of an F-V converter 51 is held for a preset time by a holding circuit 83. The stripe pattern of the seams of the tape 3 generates the holding signals in correspondence to the point of the sensor 4 to prevent the generation of excessive noises due to the error of the stripe intervals of the seams so that such fine rotational irregularity can be metered by accomplishing sufficient signal amplification of the downstream stage
