MEASURING UNIT FOR GRAVITATIONAL GRADIOMETER Russian patent published in 2018 - IPC G01V7/02 G01D3/28 G12B7/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrumentation, in particular to precision measuring devices, and is intended for obtaining high-precision three-component values of gravity acceleration along mutually orthogonal axes characterizing the gravity vector at a given point of space in order to form an array of data for the complex study of the gravitational field. Measuring unit for a gravity gradiometer, comprising a housing having an outer casing and an inner casing, a group of high-precision accelerometers located inside the inner casing, a thermostabilization system consisting of a controller, temperature sensors and heaters and located inside the inner casing, a digital data processing system and external interface, a power system interface, while temperature sensors are located both on the outer surface of the inner shell and inside it.

EFFECT: increasing the accuracy of measuring the magnitude of the components of the gravitational gradient tensor by creating a body of two insulated casings, monitoring the temperature of the inner shell from outside and inside it.
