Abstract

PURPOSE: To enhance the measurement accuracy by a simple structure by mounting the acclerometer integrally with the displacement detection means.
CONSTITUTION: The accelerometer 5 is mounted on the displacement meter 1 integrally therewith in a mechanical point of view, and the adding circuit 7 is connected to the accelerometer 5 through the integrator 6. Thus, the detector 10 of the displacement meter 1 detects the vibration displacement X2 transmitted from floor 3 through the strut 4 and the siaplacement X1 of the rotating member 2 as impedance change of the coil 11 and the signal e1 corresponding to (X1-X2) is outputted. The accelerometer 5 detects the acceleration due to the displacement X2 of the detector 10 itself and outputs the signal corresponding thereto. The signal e2 is integrated twice by the intergrator 6 to be signal E2 which is added to the signal e1 in the adding circuit 7 and the measurement signal E0 precisely corresponding to the displacement X1 in which the error due to the vibration displacement of the detector 10 itself is removed is outputted.
