Claims (3)

1. Воспринимающее устройство для измерения положения, ускорения или гравитационного поля и компонентов его градиента, включающее в себя сферическую полость (3) и измерительные датчики или измерительные электроды, пространственное расположение которых соотносится с тремя взаимно независимыми осями координат x, y, z, причем все указанные датчики реагируют на общую инертную массу, которая заполняет полость (3), отличающееся тем, что общая инертная масса представляет собой вещество датчика в виде текучей среды или какого-либо иного инерционного материала, обладающего свойством текучести, вещество датчика полностью заполняет полость (3) и реагирует на колебания давления, вызванные ускорением так, что происходят изменения в распределении величины физического поля или свойств материала датчика, измерительные датчики или электроды приспособлены для измерения указанных изменений.1. A sensing device for measuring the position, acceleration, or gravitational field and components of its gradient, including a spherical cavity (3) and measuring sensors or measuring electrodes, the spatial arrangement of which corresponds to three mutually independent coordinate axes x, y, z, and all these sensors respond to a total inert mass that fills the cavity (3), characterized in that the total inert mass is a sensor substance in the form of a fluid or some other inertial mass about a material with a flow property, the sensor substance completely fills the cavity (3) and responds to pressure fluctuations caused by acceleration so that changes occur in the distribution of the physical field or the properties of the sensor material, measuring sensors or electrodes are adapted to measure these changes. 2. Воспринимающее устройство по п.1, отличающееся тем, что через центр полости (3) проходят три оси координат x, y, z, перпендикулярные друг другу и снабженные измерительными датчиками или электродами (-x,+x;-y,+y;-z,+z), по меньшей мере, в местах размещения на внутренней поверхности полости (3). 2. The sensing device according to claim 1, characterized in that three coordinate axes x, y, z pass through the center of the cavity (3) and are perpendicular to each other and equipped with measuring sensors or electrodes (-x, + x; -y, + y ; -z, + z), at least in places of placement on the inner surface of the cavity (3). 3. Воспринимающее устройство по п.1 или 2, отличающееся тем, что измерительные датчики реагируют на изменение давления в веществе датчика. 3. The sensing device according to claim 1 or 2, characterized in that the measuring sensors respond to pressure changes in the sensor material.
