FIELD: geophysics.
SUBSTANCE: sensor comprises source of gravity field and gravitational vibrator. The source is made of the spherical gravitating body that is provided with the concentric spherical space and ring recess along the plane of the large circumference and filled with the agent whose density is less than that of the gravitating body. The gravitational vibrator is mounted at the center of the concentric space and made of a rod provided with two testing bodies. The bearing is mounted at the middle of the rod. The gravitating body is made of a magnetically soft material, and the testing bodies are made of an alloy whose diamagnetic permeability is compensated by the paramagnetic permeability of the admixtures. The sides of the spherical space are covered with the material-alloy of the testing bodies.
EFFECT: enhanced precision.
