Вертикальный гравитационный градиентометр, содержащий вакуумированный корпус, в котором установлены два разнесенных по вертикали цилиндрических резервуара с рабочей жидкостью, например ртутью, и размещенными в них поплавками, образующих верхнюю и нижнюю гидростатические системы, при этом верхний поплавок жестко связан с нижним резервуаром и через осевой стержень - с одним из двух пар дифференциальных струнных преобразователей, а нижний поплавок жестко связан с верхним резервуаром и корпусом, причем в каждой гидростатической системе геометрические параметры резервуаров, поплавков и ртути находятся в соотношенииA vertical gravity gradiometer containing a vacuum housing in which two cylindrical reservoirs with a working fluid, such as mercury, spaced vertically, and floats placed in them, forming the upper and lower hydrostatic systems, are installed, and the upper float is rigidly connected to the lower reservoir and through the axial rod - with one of two pairs of differential string transducers, and the lower float is rigidly connected to the upper reservoir and the housing, and in each hydrostatic system eometricheskie parameters tanks, floats and mercury are in the ratio

где Q - площадь горизонтального сечения поплавка по урезу ртути; S- площадь свободной поверхности ртути; Vfl - объем погруженной части поплавка; VHg - объем ртути, отличающийся тем, что поплавки выполнены из материалов с большим коэффициентом теплового расширения, например из дюралюминия, а резервуары - из материалов с малыми коэффициентами теплового расширения, например из инвара, причем обе пары струнных преобразователей прикреплены к осевому стержню верхнего поплавка и расположены во взаимно перпендикулярных вертикальных плоскостях с одинаковыми номинальными натяжениями, а их результирующие направлены по вертикали в противоположных направлениях.where Q is the horizontal cross-sectional area of the float along the mercury edge; S is the free surface area of mercury; V fl is the volume of the submerged part of the float; V Hg is the volume of mercury, characterized in that the floats are made of materials with a high coefficient of thermal expansion, for example, of duralumin, and the tanks are made of materials with low coefficients of thermal expansion, for example of Invar, both pairs of string transducers attached to the axial rod of the upper float and are located in mutually perpendicular vertical planes with the same nominal tension, and their resulting are directed vertically in opposite directions.
