PROBLEM TO BE SOLVED: To provide a triaxial superconduction accelerometer having impact resistance, facilitating manipulation, and capable of measuring micro acceleration with ultrahigh resolution and without resistance due to a hinge, as well as being triaxially freely displaced and precisely measuring triaxial acceleration, by supporting an inertial mass without the use of the hinge. SOLUTION: In a magnetic-shielded inertial space, an inertial mass 3 formed of a superconductive spherical body is floated and held by the Meissner effect in a spherical space formed by a combination of permanent magnet pieces 5. When accelerated, the inertial mass 3 having complete diamagnetic properties is displaced in the accelerated direction, varying the separation from the permanent magnet pieces 5 and the magnetic flux density. The variation is measured by each SQUID flux meter 10 that employs the Josephson effect. |
