<p>PURPOSE:To execute the measurement with high accuracy by holding a bar-like electrode through an insulator in at least four pieces of small holes of an outer wall of a spherical container in which a conductive liquid or a particle-like solid is sealed inside, and measuring and calculating an electric resistance between its electrodes. CONSTITUTION:At least four small holes 5 are provided on an outer wall of a spherical container having conductivity, and in the small hole 5, a bar-like electrode 2a is inserted in the direction for looking at the center of the container 1 through an insulating electrode holding implement 3, and the inside of the container 1 is sealed with a conductive liquid or a particle-like solid 4. In this state, by a variation of the acceleration direction, the solid 4 moves in the direction reverse to the acceleration direction, therefore, electrode height at which the electrode 2a comes into contact with the solid 4 is calculated from a measured value of the potential of the electrode 2a, and the acceleration direction is derived.</p> |
