DEFORMATION METER Russian patent published in 2007 - IPC G01V1/16 

FIELD: geodetic instrument engineering.

SUBSTANCE: deformation meter can be used for measuring deformation of surface of the Earth. Deformation meter has bed, rod, which rod has one end tightly connected with bed by means of split bushing, and the other of rod is connected with technological pin by means of collet clamp. Technological pin is mounted onto rod in axial of magnetostrictive pin. Solenoid is reeled upon the pin. Deformation meter also has rhombus-shaped fixing member, which has cone-shaped pinches at corners. Magnetostrictive pin is tightly fixed in corners of fixing member along its shorter diagonal and it has one end connected with technological pin. The other end of magnetostrictive pin is connected with elastic equal-sized parallelogram shift amplifier, which has cone-shaped pinches at corners. Pinches are connected by pins in one corner along shorter diagonal by differential photosensitive elements. At the opposite corner it is fastened by metal screen having rectangular opening in center and with light-emitting diode, disposed in perpendicular to screen. Planes of photosensitive element and of screen are parallel to plane of shift amplifier. Photosensitive element and light-emitting diode are disposed in symmetry to opening in screen at different sides of screen. Registrar is connected to photosensitive element. Movable part of adjusting unit has cone-shaped recess and it is connected with one angle of shift amplifier by means of cone-shaped rod along longer diagonal. Motionless part of device is connected with reversible engine provided with reduction box.

EFFECT: improved precision of measurement.
