摘要: A self-erecting tiltmeter includes a vertical seeking assembly suspended on gimbals within housing which contains viscous fluid. Portions of the outer surface spherically match corresponding portions inner surface, leaving gap or gaps across fluid may transfer tilts to assembly. Different have different radii curvature. The is sufficiently dense as reduce weight gimbals. conductivity difference bubble sensor assembly, signals from are transmitted exterior through wires pass pivots An annulus closed cell neoprene accommodates thermal expansion
