Abstract
PURPOSE: To perform highly accurate measurement of displacements by constituting the apparatus with a detecting face composed of two lines of grooves or the like of the spacing varying along the axial direction of a rotator, a non-contact type sensor provided with a spacing from said detecting face and a processing circuit for the signal from the sensor.
CONSTITUTION: Tow lines of grooves 1a, 1b of a spacing varying along the axial line direction of a rotator 1 are provided to constitute the detecting face A. A sensor 2 which is a non-contact type displacement meter is supported by a supporting means 3 and is disposed in the direction where its axial line is at a right angle to the axial line of the rotator 1. It opposes to the detecting face A of the rotator 1 by leaving a spacing. This spacing is suitably adjustable. The signal from the non-contact type displacement meter 2 is processed in the processing circuit B consisting of an amplifier 4, high pass filter 5 and low pass filter 6, thus the respective displacements in the axial line direction of the rotator 1 by the filter 5 and orthogonal to the axial line direction by the filter 6 may be measured with good accuracy.
