| Abstract: | The gravity accelerator adopted the method of measuring pendulum length by capacitive digital caliper displacement sensor.The diagraph of variety of simple pendulum could be measured in high precision,and the influence of the vibrator dimension and the deviation of the gravity center could be avoided.The period of simple pendulum was measured more accurately by an additional timing installation with high precision;hence the precision of acceleration of gravity was raised. |
