MEASURING DEVICE OF GRAVITY FORCE Russian patent published in 2009 - IPC G01V7/00 

FIELD: measuring technology.

SUBSTANCE: invention refers to instrument engineering and can be used for measurement of gravity force. According to the invention, the device consists of a double quartz flexible system of a torsion type with horizontal pendulums and mirrors secured thereon; the system is enclosed with a case filled with a damping liquid; also the device consists of a photoelectric converter including a source of radiation, a lens, an auto-collimation mark installed in focal plane of the lens and a photoelectric receiver arranged in a conjugated focal plane of the lens; notably, a specialised mega-pixel TV-camera on CMOS-structure (complex metal oxy-semi-conductor) operates as a photoelectric receiver; the output of the camera is connected to USB-port of PS, while input is connected to a block of synchronisation also connected to the source of radiation. The photoelectric converter is secured on the case of the flexible system and rotates around optical axis. The flexible system is inserted in the case of the thermostat, on side walls of which there are fastened semi-conducting modules with radiators. In a lower part of the thermostat base there is installed a fan, while the case of the thermostat is rigidly fixed on the base via a heat-insulating plate and is covered with a heat-insulating material.

EFFECT: facilitating upgraded accuracy of wide range gravimetric measurements at changes of temperature of environment.
